I know nothing about law enforcement other than I don’t really trust law enforcement but I think this sounds like a great route. Nobody will hate you, you’ll be in scary situations but rarely ones where you’re scared OF people (which will scar you forever - speaking as someone who’s best friend is a cop and is all sorts of fucked up), and you’ll be performing an excellent service to the community. And it seems like you’ll do law enforcement in the end, according to this comment. Plus everybody loves a hot firefighter.
