SWAT is scary looking by design. The more scary the less they may have to shoot.
However, it's all about software. The more they train, the less they shoot. The problem is, and may always be, that the brass gives them the hardware, but no training. You can count the HK54s and report to the city council about them being in inventory, however just go ahead and justify training costs!
But, they're cops, they're already trained.
The SWAT guys who understand their role are wonderful. They understand that they are not "going to war."
What I object to the SWATification of the patrol officer who may not understand that he is not "going to war." For example, the outrageous conduct of the Virginny mall ninjas wearing masks and pointing carbines at motorists during the alleged mad dog snipers in East Coast Eloi land. That was an outrage over which I still shudder.
The purpose of the police is to gather evidence and report to the prosecutor. Nothing more, nothing less. They are not around to "protect" anyone. They are not to make war on anyone.
However, I believe this problem is tied to the Welfare State. People sit on the couch and demand the government "do something." Until we address this, we will have problems with police, intentionally or unintentionally, threatening our liberty.
