And please don't send me 300,000 URLs that would be way too much work....
Wouldn't need to. From my recent research, almost every major metropolitan I looked into either already has cameras or are in the process of getting them, or at the very least are talking about getting them. It wouldnt take too much effort to tally enough large police forces together (after verifying they are or will be using cameras) to meet the threshold required to create an accurate statistical projection. A projection, that I assume, only needs to meet half of the total number of active duty police (another number easily accessible).
While it would take a while, it would be relatively easy to do.
Of course if you are talking about total police organizations and not individuals, I couldn't really help. In fact given how many small, underfunded police, sheriff, marshal, etc... departments there are in this country I'm more than certain less than half can even afford these cameras let alone already have them or plans to get them.
Doesn't mean they all need them either.
Anyway, here's some relevant factual information everyone can use. Information was taken from cnn.com:
Here are a few things to know about how the grand jury system should work as it pertains to this case and others in Missouri -
Is the grand jury the only way that a person can be charged with a crime?
No. In fact, it's not the way most people are charged with crimes. It's used by prosecutors only in a small percentage of cases.
Authorities can file a criminal complaint, which could then lead to a probable cause hearing in court. Such a proceeding is open to the public and media.
That's not the case with a grand jury proceeding.
So it's closed to the public?
Yes.
How is a grand jury picked?
Just like any other jury. Citizens get a summons in the mail telling them to come to court. If they make the cut, they are on a grand jury.
In this case, the jurors will come from St. Louis County, Missouri.
How many people are on a grand jury?
In Missouri, it's 12 people. (The number might be different in other cases.)
So what are the grand jurors deciding?
According to the Missouri state attorney general's office, a grand jury is looking at two things. One, was a crime committed? Two, is there probable cause that the accused -- in this case Officer Darren Wilson -- committed the crime.
It is very significant that this is a lower standard than for a criminal trial. In that case, jurors must decide if someone is guilty of a crime "beyond a reasonable doubt." "Probable cause" isn't as stringent.
Does their decision have to be unanimous for a charge to be filed?
No. It's true that, in a criminal trial, all jurors must agree to convict someone on a given charge. But in Missouri only nine jurors -- or three-fourths of the grand jury -- have to agree.
Is the process overseen by a judge?
No. As Neil Bruntrager, a criminal defense lawyer and general counsel for the St. Louis Police Officer Association explains, it's just the grand jurors, the prosecutors and the witnesses. That means no judge or defense lawyers.
"The prosecutor simply presents the information that they have," Bruntrager explains.
Does that mean the accused can't present a defense?
Yes and no.
First off, unlike during a regular trial, defense lawyers can't rebut the prosecution or cross-examine a witness. It's the prosecutors who present their case, without interruption.
That doesn't mean that the voice of the accused isn't heard. As the attorney general notes, "defendants do not attend unless they are testifying as witnesses." Since Darren Wilson witnessed what happened on August 9 as much, if not better, than anyone else alive, he might be invited to testify in court.
"Usually an accused will not be invited to testify," Bruntrager told CNN. "But I would expect, in a case like this, that an invitation would be extended to him."
What will the prosecution present to the grand jury?
In a word, everything.
Just take McCulloch's word for it, according to the Wall Street Journal: "Absolutely everything will be presented to the grand jury. Every scrap of paper that we have. Every photograph that was taken."
Will McCulloch himself present the case?
Ed Magee, a spokesman for the prosecutor's office, told the St. Louis Post-Dispatch that the prosecution will be "handled by the attorney regularly assigned to the grand jury. It will not be by Mr. McCulloch."
So how long will this process take?
A grand jury could indict some one as early as tomorrow. But that doesn't mean it's going to happen that fast. In fact, it could be weeks or months.
After all, U.S. Attorney General Eric Holder has said the Justice Department -- conducting a parallel federal civil rights investigation into this case -- has interviewed hundreds of potential witnesses. There's no reason to believe local authorities haven't similarly conducted lots of interviews and collected various pieces of evidence to sort through and present to the grand jury.
Doing so should take some time.
