Seconds after a judge handed down a 50-year prison sentence for murder, the convicted man turned and punched his own defense attorney in the face, sending the courtroom into chaos and prompting deputies to swarm the defendant.
The violent outburst, captured on courtroom video, unfolded in a Las Vegas courtroom on Wednesday after 33-year-old Daishan Glasper was sentenced for the 2022 fatal shooting of Javon Briggs. The Daily Mail reported that Glasper struck his attorney, Clark County Deputy Public Defender Aaron Sievert, immediately after the sentence was read aloud by Clark County District Judge Tierra Jones.
The attack raises sharp questions about courtroom security, the safety of defense attorneys who represent violent offenders, and whether the incident will bring additional charges against a man already facing decades behind bars.
Glasper had been convicted of second-degree murder with a deadly weapon in the shooting death of Briggs, who was killed on December 5, 2022. The conviction carried a sentence of 50 years in Nevada state prison.
Courtroom footage shows Judge Jones finishing the sentencing pronouncement. Glasper, standing beside Sievert at the defense table, appears calm for a brief moment. Then, without warning, he turns and delivers a closed-fist punch directly to Sievert's face.
Deputies in the courtroom reacted within seconds. Multiple officers tackled Glasper and forced him to the ground, restraining him as the courtroom erupted. Sievert stumbled but remained on his feet. He appeared shaken but did not require emergency medical transport from the courtroom.
The entire sequence, from sentence to takedown, lasted only a few seconds. But the footage spread rapidly online, drawing millions of views and renewed attention to the dangers attorneys face when representing defendants in violent felony cases.
The underlying crime dates back more than two years. On December 5, 2022, Javon Briggs was shot and killed in Las Vegas. Glasper was identified as the suspect, arrested, and charged with murder.
Prosecutors pursued the case as second-degree murder with a deadly weapon enhancement, a charge structure under Nevada law that allows for a substantially longer prison term than a base murder conviction. A jury found Glasper guilty, and the case moved to sentencing before Judge Jones.
Glasper's defense team, led by Sievert through the Clark County Public Defender's Office, represented him through trial and sentencing. Public defenders in Nevada, as in most states, are constitutionally required to provide representation regardless of the severity of the charges or the defendant's behavior. That obligation does not, of course, include absorbing a punch to the face.
Courtroom confrontations between defendants and their own attorneys, while not unheard of, remain rare enough to shock even veteran court observers. The incident echoes other moments of courtroom tension in high-profile criminal trials where the proceedings themselves become scenes of disorder.
The attack has drawn attention to the physical layout and staffing of courtrooms handling violent felony sentencings. In the video, Glasper does not appear to be handcuffed or physically restrained at the time of the punch, consistent with standard courtroom practice during formal proceedings. Defense attorneys typically stand beside their clients at sentencing, often within arm's reach.
Clark County courts generally station armed deputies inside courtrooms during felony proceedings. In this case, the deputies' response was fast. But the punch still landed cleanly, raising the question of whether additional precautions should apply when defendants face lengthy sentences for violent crimes.
Legal observers have noted that the moment of sentencing is among the most volatile in any criminal case. A defendant hearing a decades-long sentence has, in a practical sense, nothing left to lose. That reality creates a window of danger for everyone in the courtroom, from judges and attorneys to clerks and spectators.
Glasper now faces the prospect of additional criminal charges stemming from the assault on Sievert. Under Nevada law, battery on a person in a protected category, which can include officers of the court, carries penalties that could be stacked on top of his existing 50-year sentence.
Authorities have not publicly confirmed whether new charges have been filed as of the time of reporting. The Clark County District Attorney's Office would have jurisdiction over any such decision. Given the clarity of the courtroom video, which shows the punch from multiple angles, prosecutors would face few evidentiary hurdles if they choose to proceed.
The incident also raises the question of whether Glasper's conduct could affect any future appeal of his murder conviction. While a post-sentencing assault on counsel does not directly alter the legal posture of the underlying case, it could factor into judicial discretion on procedural matters down the line.
Violent outbursts inside courthouses have drawn increasing concern in recent years. Federal prosecutors have shown a willingness to pursue assault charges aggressively when violence occurs in settings tied to legal proceedings, and state prosecutors in Nevada have followed a similar pattern.
Sievert's situation highlights a tension embedded in the criminal justice system. Public defenders are ethically bound to advocate zealously for their clients, even clients convicted of murder. They sit beside those clients, speak on their behalf, and absorb the emotional weight of cases that often end in long prison terms. And sometimes, as Wednesday's footage made viscerally clear, they absorb physical violence too.
The Clark County Public Defender's Office has not released a public statement about the incident. Sievert's condition beyond the immediate aftermath has not been publicly disclosed.
Defense attorneys across the country have pointed to the incident as a stark reminder of the occupational hazards they face. Unlike prosecutors, who sit across the courtroom and are typically separated from defendants by distance and deputies, defense lawyers work in close physical proximity to people convicted of serious violence. That proximity is by design. It is also, on days like Wednesday, a source of real danger.
The broader pattern of volatile defendants and chaotic courtroom scenes has pushed some jurisdictions to reconsider security protocols, though changes have been slow and uneven.
Glasper's 50-year sentence for the murder of Javon Briggs means he will not be eligible for release until well into his eighties, assuming no sentence reduction. If prosecutors add a battery charge for the attack on Sievert, that timeline could extend further.
Briggs's family, who were present in the courtroom for the sentencing, witnessed both the sentence and the assault. Their reaction has not been publicly reported in detail, though the courtroom video shows visible shock among spectators as deputies wrestled Glasper to the ground.
The case has drawn comparisons to other criminal trials where the courtroom itself became a flashpoint, reminding the public that the controlled environment of a courtroom is only as secure as the people inside it allow it to be.
Judge Jones cleared the courtroom after the incident. Proceedings were suspended for the remainder of the day.
Investigators and prosecutors will need to determine whether to file additional charges against Glasper for the assault. They will also need to assess whether the incident warrants changes to courtroom security procedures for future high-stakes sentencings in Clark County.
Authorities have not publicly confirmed whether Sievert intends to pursue any civil action related to the attack. Such claims, while legally available, are rarely pursued by public defenders against former clients.
The courtroom video, meanwhile, continues to circulate. It is a few seconds of footage, but it captures something that statistics and policy papers cannot: the raw, unfiltered moment when a convicted killer lashes out at the one person in the room who was required by law to stand beside him.
When the system guarantees every defendant a lawyer, it also guarantees that lawyer a front-row seat to whatever comes next. On Wednesday in Las Vegas, what came next was a fist.
