Floyd's killing sparked global protests as people from many different communities joined together to call for an end to racism and police brutality. But for some Americans, the fear of police violence is greater than for others.

What will we hear and see from the courtroom?
Once proceedings start today, we will hear from potential jurors in the Minneapolis court as they are questioned about eligibility.
It's a huge departure from convention for TV cameras to be inside a court in the state of Minnesota.
But we won't see pictures of the citizens being questioned - instead the cameras will capture the judge, lawyers and the witness stand.
And the day will be punctuated by the moments when people are struck off the list of potential jurors.
Our correspondent Tara McKelvey is in Minneapolis and will be bringing us the latest from the proceedings.

It’s a contentious process, and quite different to what happens in the UK. Lawyers for both sides will be able to question as many as hundreds of jury candidates to eventually choose 16.
Potential jurors have already been asked for details over their knowledge of the case, contact with police and media habits.
Either side can remove a possible juror from the pool but the opposing side could also issue a challenge if they believe the person was removed due to discrimination based on race, ethnicity or gender.
The judge then decides whether the juror stays or goes.In the UK, juries are selected at random. They are not subjected to cross-examination and are only dismissed by a judge in extraordinary circumstances, like if they know a victim. Jurors also don't know which trial they will serve on until they've been sworn in to help avoid pre-judgement.
It began with a pack of cigarettes. George Floyd, 46, bought them at a convenience store in Minneapolis, Minnesota, on 25 May 2020.
A shop assistant believed he had used a counterfeit $20 bill and called the police after Mr Floyd refused to give the cigarettes back.
Police arrived and handcuffed him, but when they tried to put him into the squad car he resisted, and a struggle ended with Floyd face-down on the street.
Officer Derek Chauvin, 44, placed his left knee between Floyd's head and neck, and kept it there for seven minutes and 46 seconds, according to prosecutors.
Two other officers helped pin him down, while another prevented witnesses from intervening.
Floyd told officers he could not breathe more than 20 times. Video of the incident shows him go limp and get carried away by police.

Hundreds of people gathered for a "I Can't Breathe" Silent March for Justice on Sunday in Minneapolis where George Floyd was killed.
More protests are expected later today.
Many in black communities and supporters of the Black Lives Matter want to see justice served for George Floyd.
But there is a lack of trust in the legal process which many believe has historically been biased in favour of law enforcement and white suspects.
"I hope that our legal system allows all evidence to be presented and that we get a conviction, but I don't expect it," one protester told AFP news agency on Sunday.
The verdict in the trial is not expected until late April but it's almost certain there will be more protests before then.
What's happening today?

From Monday, the court will start to pick a jury of 12 people who will hear the trial of Derek Chauvin. Four additional people will be picked to be alternatives.
These people will determine the outcome of the trial and in such a high-profile case, the court will want to try to ensure jurors will be able to judge Chauvin fairly.
Four potential jurors will appear in court each morning and afternoon to be individually questioned in a process that could take weeks.
Eligible citizens have already received a 16-page questionnaire asking about their familiarity with the case, news habits and interactions with police, among other things that may affect their judgement.
Both sides can ask the judge to dismiss a potential juror "for cause" if they perceive a bias or conflict under questioning.
They can also use a limited amount of "peremptory challenges" to remove that person from the pool without giving a reason - the prosecution has nine of these and Chauvin's defence team has 15.
If either side suspects someone has been discriminated against because of something like sex or race - their dismissal can be objected to.

On Monday, the process to decide who will serve in the jury of Derek Chauvin's trial will begin.
