It seems like your just fishing for a “small dick energy” as a response to validate your feelings and to virtue signal. I can guarentee if you actually asked him why he feels the need to he would reply with 1. Why do I need to have a need 2. There’s no reason not to if following all appropriate laws. Stop generalizing people who owns guns. That guy could be the biggest liberal for all you know. He could’ve just come from the range and only had an out of waistband holster. There’s next to zero gun crime in Maine so I wouldn’t be too worried.

Ps. Most gun owners I know are extremely anti police. Stop making judgements on the world based off your predispositions derived from hive mind internet communities and groups.
