of course! You can stay there all you want. However let me point this out (nothing against anyone, not even necessarily bad, just something to think about)
In Tom's case he asked if he was being detained and was told no, the leo then went outside and called in his "entourage" and they continued to harrass Tom while telling him he was not being detained.
This goes back to what my ma's an' pa's used to been tellin me "it takes a bigger man to walk away." Sure you can stay there, however what is going to happen when you keep getting harrassed? How far will it go? Will they call buddies and place you in a situation that you can no longer leave freely?
I am not saying there is a right way or a wrong way, my personal way would be to just move along and count it as a "bigger man" victory for me.
