No, it doesn't mean the guy should've died. However, there's a process in place called the court system. That system is in place to deal with inappropriate police behavior.

You deal with a bad warrant, 4th amendment violation, etc...when you go to court. Not by raising a potentially lethal weapon over your head as if you mean to strike an armed police officer with it. Courts frequently rule against cops in search and seizure activities. If it's bad, it'll likely come to light in a courtroom.

The guy had a history of making bad decisions. This was just another in a long line. And who knows? Maybe he was under the influence of various drugs when this whole thing happened.
