Can a CSM go into POV’s without the owner present?

I believe that nearly (if not every) base or post has a sign at each entrance that advises that entry into the government post makes people and vehicles "subject to search" ("and siezure"), so the answer to this question is most likely "Yes"! ...and I echo the question below, "Why would (anyone) leave their POV unlocked?"

Read those placards posted at the main gate. By entering a military installation, you give consent to searches of your vehicle.

Look at the sign posted at every military installation that gives the commander authorization to search and control everything within the limits of his command for the health safety and welfare of such.

POV, PRIVATE OWNED VEHICLE, Enuff said. I'd punch his lights out or give him or her a free ambulance ride to the hospital. They don't pay my car payments or insurance policy

Now, idk if it’s changed or not, but, when I was in 1979 to 2000, there was a sign posted at every entry to a military base that stated ALL vehicles are subject to search and seizure ( or words to that effect) What I know wasn’t written was WHO could or couldn’t do that. It was naturally presumed that any one could do so. I remember a drug check was order for my battalion, ( dogs and so on) and people with cars had to open up their cars and let Fido sniff around them. We were all outside so the dogs could do what they wanted inside. So, I’m standing there with a brand new car ( to me) that I had purchase from someone else who just left the the military yesterday. Bought the car from him after I drove him to the airport to leave. That was my test drive. Guess who’s car Fido alerted on? That’s right. That of course is a different subject. However, do you know the reason for this senior person doing the search? It’s a SENIOR personnel searching. I’ve had my fair share of incompetent NCOs leading me. Never had an incompetent Senior NCO lead me. They just don’t get that rank if they are incompetent. Most of them are laid back. They don’t have to be the dick in situations any more unless it absolutely calls for it. Most senior NCOs genuinely care about the well being of the troops. Maybe this person was a dirt bag and this was the time to mail them. You don’t know, you can’t judge. I know I’m not gonna act unless it calls for me to act. During my time in, the CQ or Duty NCO on up had the right to inspect anything at anytime.

You give up some rights to privacy when you enlist without question. But just because you have a batch of stripes on your arm you don't suddenly inherit the right to violate your 4th Amendment rights or other constitutional rights. If you disagree I ask whether it would be ok if this CSM were to enter your base housing because he wanted to?

My only experience is on high security FBM Submarine bases, and it's right there in black and white as you go in - entry onto the base constitutes right to search.

NO

You're in the service and must know about all the dirtbags that surround you. Yet you leave your vehicle unsecured. Really?

Parking lot Gov. Property. Then there you go! Uncle Sams.
