I was at my job , parked on the front parking lot, open to visitors ( I'm not sure if is private or not) I found my glass broken, the grass was fresh , I found out that personel from maintenance was cutting the grass, and they admitted it, but didn't say if they broke the glass, there is a camera outside but it is not working, I asked the outsoursing company owner if there was any economic compensation , but she said there was no proff, and that it is considered a public parking lot, that I should deal with it on the police as a private incident. But she told me we couldn't look at the cameras either, that they were for the company security onlu, so what do I do? In this case, please help me out.

If you have insurance on your car that covers broken glass turn the claim over to your insurance company and include all the other pertinent information.
