At a 'town hall' in Golden about 10 years ago, someone from Tom Tancredo's office indicated that was willing to accept lethal collateral damage in the regular course of law enforcement, including mistakes leading to application of the death penalty.
His reasoning was that people who find themselves faced with no-knock warrants, or falsely implicated in capital crimes, are probably guilty of something even if they are innocent of the matter of present concern.
I find that sentiment difficult to comprehend, but I imagine that citizens who only experience the 'services' of police tend to forget that people living a few blocks away may have a very different relationship with law enforcement.
