There are many jobs that are much more dangerous than cop and still, I don't hear à lot of conservatives telling their heart goes ot the famillies of roofers, minors, loggers, etc...
Alos, there's one thing I do not understand : conservatives are mostly gun-enthusiast, they say they need their gun, for self defense, 'cause police is not efficient (take too much time ot come if you're home is being attacked or there's is never a cop in the neighborhood when you need one). But still, they will always defend cops who murdered unarmed civilians.
