If your ultimate goal is to go into law enforcement, I'd recommend getting some type of degree and only working part-time rather than going full-time in a security job. The security experience won't count for as much now, as most agencies are looking for education and life experience over security experience.
David is correct. A security job depends heavily on the type. It is fine to pay the bills, but most types will not help you land a job with a law enforcement agency. A military background will help you in California tremendously! Being a veteran shows you have discipline, maturity and a strong sense of service and teamwork. That is ideal not only for the streets but especially for SWAT! I myself was a military working dog handler (K9) in the USAF. I also always recommend becoming a reserve officer to make sure this is what you want to do. No money, but it will help you for sure if you apply for a full-time position. As far as a degree, I also recommend getting that degree in something OTHER than law enforcement! The reason? If you decide LE is not for you, or if you become disabled on the job, you have something to fall back on. An LE degree will not help you in much beyond the LE field. ANY degree will help you promote in LE and/or land a job.
Good luck Chris. There will always be job security in law enforcement and SWAT is definitely a goal to set your sights on but you have to pay your first!
