well id suggest you read it again if that was your only take from the comment. also does, or does not, police reduce crime at a big festival, or at a demonstration or any other gathering of people? Do police regulating traffic reduce traffic accidents by enforcing traffic laws?

Ever heard of gang ruled areas? those can exist because of underfounded police. id say those have higher crime than police controlled cities.

Also again, not at all the essense of my comment, but rather a supporting point.
