Actually you need to understand that police officer has one of the lowest death rates of all professions. Ranking about 4th I believe. Their job isn't as dangerous as they would have you believe.
PS, this is the list of the top 10 most dangerous jobs in the US, cops don’t make the list, so I was wrong about 4th place. As you can see there are other people who put their lives on the line every day just to earn a living, AND they don’t shoot other people’s dogs while doing their jobs(or kill homeless people).
