I'm a Corrections Officer, so with another prison being built in my area no worries... 
Besides, what other occupation should I have got being in the military so damn long

• Police officer
• Security consultant
• Private investigator
• Bodyguard
• US Secret Service (the majority are former military)
• Security officer/investigator with a law firm (tons of well paid work there)
• Security officer with a private corporation/organization (again tons of work here; think GE, Apple, Google, Ford, International Paper, etc.). They hire to protect property and people (company executives).
*• The private security firm business is booming both in the US and abroad. You could work for such an organization or found your own. Ever heard of Blackwater? It was founded in 1997 by Erik Prince and it has made the former Navy SEAL a ton of money.
It is not really about where you could go or what you could do. It has to do with how imaginative, resourceful, and entrepreneurial you are. Though you sort of answered that with your question above.
*True story: Marc Benioff (the billionaire CEO of Salesforce.com) lives near me on a street the locals call "Billionaire's Row." Obviously, his house is huge and he routinely travels with security. He also has a security team for his house… but he and his wife didn’t want the security guys roaming around their house and always in sight. So they bought the huge house next door, and put all their security people over there… where they can be summoned with a shout or the push of a button. Is their house likely to be burglarized? No. All things considered, I would say it is an easy gig, but you can bet their security folk are very well paid.
