Legal Answers
2 Questions Answered
Q. How can I be charged with unlawful possession of a firearm not being a felon and not committing a felony.
A: There’s no way to know without seeing all of the evidence that is in the possession of the state. You have a right to something called discovery - this is the formal name for the process by which the parties to a legal proceeding gather facts and information in possession of the other party. In criminal cases specifically, a defendant has a right under what is known as the Brady Rule, from a famous 1963 Supreme Court case and subsequent law, to inspect the evidence in possession of the state. This is typically one of the first steps that a criminal attorney will take - motions for disclosure of state’s evidence.
Q. I'm in the process of getting my medical marijuana card. Can I still possess and own a fireaem if I get my medical card
A: As of now, one who has a medical marijuana card in Missouri cannot purchase or own a firearm. This is not due to Missouri law, but rather the fact that cannabis is still federally classified a controlled substance This is a quickly-changing area of the law as there is pending federal legislation which would legalize cannabis at the federal level. But as of right now - no, you cannot legally own or possess a firearm with a medical marijuana card.
