Is it recommended to mention this to the PD? I assume no right?Remembering my college days, partying at friends' off-campus apartments, I would NEVER leave guns/valuables in an off-campus apartment. A lot smarter to store your guns at your parents' home and retrieve them when you need them. NOTHING was secure during those parties, nothing!
Likely you have a 9 month lease just for the school year and may be in a different apartment the following school year. That doesn't make your student apartment very "permanent", I'd use your parents' address for everything and I doubt that any PD would have a problem with that.
