Again, this is not meant to belittle the death of police officers. I would not want someone to belittle the death of a construction worker. Still, it's worth reminding people that being a police officer isn't nearly as dangerous as PBAs would like to have you believe. It's also worth noting that claims about the perceived danger of being a police officer are almost always used to justify the militarization of the police, the violation of civil liberties etc.
