While I agree that what he did is really odd, it would be legal in Missouri. I'm shocked MO is more lenient than OK on gun laws. Remember the Mike Brown thing? The dudes on the streets with their ARs? Pretty sure they were left alone. Meanwhile loudmouthed, drunk, Missouri state senator Jamilah Nasheed was arrested with a gun in her purse. I highly doubt she was prosecuted, or even had her CCL revoked (if she had one), even though both should have happened by law. I'm sure she got special treatment as she was just profiled for sitting during the pledge of allegiance during a senate session.
It would have been a hate crime to prosecute her.
