What would you do. READ BELOW?

I was at my store unit and my code was now working so I Parked my truck and walked pass the security gate as cars were coming out and I noticed a red Ford truck that had left came back into the gate and as I was walking back and I could not get out the gate I hoped over the gate and I saw that same red Ford truck watching me as I left leap back over the gate and get in my truck and leave. As I get to work the manager called me and. Said someone saw you hop the gate and got my tag #. An she said the guy to call her was that red Ford truck.

That guy could have approached me and ask me what's going on instead of snitching and called the manager and police.

Any thoughts

Yes, my thought is that you have too much time on your hands.

How would they know you weren't stealing from the place and would harm them if they were to confront you? Everybody did the right thing except you.

I know you are seeking agreement to validate your feelings, but it's not the other tenants responsibility to investigate, but is to report suspicious activity.

I wouldn't have BLOCKED the gate in the 1st place. You should consider yourself fortunate if the phone call is the worst that happens to you.
Under the terms of your contract, you could be told that you have breached the terms of your lease, and you have X days to empty the unit or the contents will be sold.

It sounds like the guy did the right thing. You, not so much.
