I agree. If they were smart, they would have had all the guns AND magazines UNLOADED and in LOCKED container in the TRUNK with another keyset. If cop asks what is in the trunk, answer is "get a warrant".
Id really like to see the vehicle they were in. I bet if the cop could look inside the vehicle and see a bunch of tactical gear, magazines, knifes, and ammo, it might past muster as a "terry look/pat". Depends on the demeanor of the suspects and if they were stupid enough to give consent to search the car. If they did...they are hosed in NJ/NY even with FOPA protections.
Look at the picture, one magazine is singled out on a piece of paper reading “plain ...”
I’d bet the paper says “plain sight”.
A magazine in “plain sight” would definitely invite a high degree of scrutiny in NY.
