Heli just flew over my place, should I be worried?

I know this is a stupid question but im ripped and was just smoking a cig outside and saw a heli fly overhead with a dome-type looking radar type thing hanging underneath the front of the heli. It didn't circle over neighborhoods just went in a straight line until I couldn't see it anymore.

Coincidence or should I be worried? 400W HPS is all I got.

I don't think they can pick up a 400W, maybe a 600W or 1KW. Next time get the RPG out and start shooting!

theyd need a warrant to do that anyway, so if they did search, they got a warrant from suspicion, most likely just flying by
