Is he interested in me?

so I met this guy from my friends last semester in my college. He always hit on me and said a lot of vulgar things but he was always pretty funny. but he was never that nice to me he would flirt with me one sec then the next make fun of me.
I realized he was a campus police also
I haven't seen him in a while until today and he looked so great in his uniform tbh it turned me on and he went out his way to talk to me and say hi and he was super nice to me. Now I'm kinda interested but im not sure how to go about it or if he's even into me. What do you think?
Is he interested in me?
