One thing that kind of stuck out was that you were walking with a group of your friends who were drinking in public, and you were high. I don't mean to be crass but you were basically waiting to get picked on in the city. It seems like the cop had thought you were in possession of drugs.

Apart from that, I think that there are a lot of details that are missing that could have shed more light on why you were treated as such. The officers comments, however, are not the kind that I would expect a police man to say.

In other places, such as the UK (the dialect of which French students are taught), "high" means "drunk".
