Good post.  I agree with every bit of that, but those aren't the ONLY relevant factors.  When you support expanding no-knock warrants to protect police officers, you also add greatly to the risk that a civilian gets shot.  Police officers are not the only people desirous of (and worthy of) living to see another day, and if you treat us as potential drug gangs or terrorist when we are not, you make yourself our enemy, not our friend.
I've read the Green Party platform as part of my desire to have a viable third option.  However, my core point here is that the Greens want to greatly empower government, and power given WILL be used.  A more powerful government will act like a more powerful government, period.
Well said, and it points out a fallacy about Oldgamer's many anti-cop threads.  Sometimes they are about the bad cops, but many times they are more about the system within which all cops work.  If that system dictates that a person being served for unpaid traffic tickets be served just as if he were the Hell's Angels prime weapons runner, that is how he will be treated by both good and bad cops.
