I AM ENRAGED! what is there left to do?

It's a long story but a cinema personnel suspected me of recording in
the cinema, i argues with them etc about 7 of them ganged up on me and
on even threatened me by getting very close to me and threatening to
fight me, another one told me that i was "pissing him off" by stating
my rights and trying to clear my name, in the end i was proven to be
innocent but they were clearly unhappy and one of them stomped his
foot suddenly to scare me while i was leaving the cinema while the
others laughed at me.

I'm so angry that i didn't say more than i did! I feel humiliated! I'm
afraid that the next time i go there they'll not let me in the
theater? Or if a personnel that remembers me treats me badly and i
voice out i'll be kicked out? Because the manager was also there and
he was obviously on their side.

What should i do? It's the cinema i visit the most because it has the
widest variety of films, the other cinemas only have blockbusters.
I did bring a camera inside but the rules outside the cinema displayed
to anyone said that no recording shall be done inside the theater, it
didn't say that i couldn't bring a camera inside and i didn't sneak it
in one of the personnel said that it has to be in the bag.
