Police and firefighters do not have particularly dangerous jobs. The unions have bamboozled the public with their dishonest advertisements.
Google “occupational death rates” to find many sources documenting dangerous jobs. Of the ten most dangerous occupations, not one is firefighters or police. Instead, ALL are private sector jobs: roofers, taxi drivers, fishermen, ranchers, farmers, etc. In other words, they are the taxpayers paying for the police and fire personnel. And generally they work way past age 50 or 55 to keep paying taxes toward those generous government pensions.
