How long before police "mistakes" are a common place?

That is not a police error unless you think that police should be required to be psychic or have some means of communicating via mental telepathy. The article said that they were initiating an arrest based upon information from a police source of an outstanding warrant. It was not until later that it was discovered that the warrant had been recalled and that the recall had not been issued on the actual warrant. Some clerk some where didn't do their job and didn't remove the outstanding warrant from the computer. So the arrest was made with info of an outstanding warrant therefore fruits of the crime are legit. If it could be shown that the police knew the warrant was invalid then there may be a case however those police can have no idea if a neighboring agencies warrant is good unless that neighboring agency tells them it is or it's not. In this case they didn't and the defendant was rightfully charged. Now if you're afraid of the police that's a personal problem. I'm not and I'm not threatened by them.. In this case good faith had nothing to do with it. There was a warrant at the time of arrest. It was recalled after the arrest and was probably acknowledged invalid because of the arrest and after the arrest.

Had the same thing (a bogus warrant) been active against me during a traffic stop, the search of the vehicle would not have resulted in any legal violations. I would have been upset, to be sure, and would likely have demanded that a written apology be provided. The matter would have been resolved to my satisfaction at that point. However, there are too many cases where criminals 'get off' on absurd technicalities, even in the case of violent crimes, only to return to the streets to continue in more of the same. Sorry, but this ruling doesn't concern me in the least in terms of the effect some seem to think it will have on 4th Amendment rights. I realize this may be an unpopular view - like the court ruling will be to many. The whole point is that this defendant is alleged to have had illegal items in his vehicle. Did he or didn't he?

Any 'deliberate' mistakes could be defended against, and so I don't see it becoming commonplace.

I might actually tend to agree with the Court on this. Too many court cases have been thrown out, along with personally reasonable evidence because someone forgot to follow protocol to the letter.

seems to me they already are, not only about the article you put up, i mean violating the constitution to the billionth degree, what were those cops thinking, but also the oakland shooting, point blank shooting a guy when your buddy has him pinned to the ground is a big enough mistake to fill up the thisshitshouldn'tbehappening meter

That's exactly what will happen.

And please notice that the guys who cry the hardest about "getting the government off our backs" are the same guys who vote for this kind of thing.

The cops acted in good faith and thought he was wanted.

Remember it is the thought that counts

Wow, and to think if he didn't have Meth in his pockets he would have walked away
