>>more force than necessary.

"Necessary" is a very subjective term, and many people disagree on what is "necessary."

For example I do not believe it is "necessary" to assume with out cause or evidence that every warrant enforcement will be a violent encounter the requires a military style response like we see here

Sure if you are going after a known violent criminal that committed a violent act (like murder). however IMO These types of tactics are not "necessary" in cases like the one we have here
