$3k/hr to catch a kidnapper is not excessive. $3k/hr to go to a chili cook off is excessive.
Police in the US act as if they are royalty. Above the law when the break it, sacrosanct when their budgets are questioned. The one thing I've notice is when they're not around, annoying behavior increases (littering, traffic, etc) but society seems to keep humming along and it doesn't collapse. I'll take the annoyances over their cost and bad behavior any day.
