Senate Bill 5737 is your typical "assault weapons" ban. Banning semi auto guns with detachable magazines, 10 round limit, etc.
The scary part is the "grandfather" provision. If you already own a semi auto, you can keep it; but the Sheriff can inspect your home once a year to ensure that you are storing it safely.
Supporters are claiming that the search provision was added by mistake, but they say the definition of a mistake in politics is when you accidentally tell the truth.
