According to a report on The Blaze, protestors in Erie, PA gathered to defy the city’s local ordinance which bans carrying firearms openly in public.

Many of the protestors carried slung rifles and some carried holstered handguns.

Police issued citations to some of the protestors, who will now face a $100-300 fine and up to 90 days in jail if they fail to pay their fines.

Police also walked around noting the license plates of cars present at the event, and will use state databases along with video of the event to mail citations to people who can be identified.

According to The Blaze, some protestors took exception to that practice,
