so, i have a friend of a friend (and i really do mean that, it's not me, just someone i know that i said i would research for) who grows medical marijuana. this person grows medical marijuana according to local laws and follows all the rules. unfortunately, they just had to move to a neighborhood that isn't very safe. their property has been shot up during random gang violence. they're afraid of owning a firearm in the case that it brings more charges down on them if the feds raid their house. the question is, if they're abiding by all the local and state laws pertaining to growing medical marijuana, how does that factor in to defending their home and property from gangs and thugs? can one own a firearm for home/personal defense when one grows medical marijuana in oregon without incurring charges? if the federal government were to raid the house in violation of local laws, would criminal charges be worse?
