To get Constitutional Carry, this is what we need:
Repeal 941.23 (concealed carry without a license), 941.235 (government building carry), 941.237 (Class-B carry), 167.31 (car carry) maybe?
Assuming we don't get the Federal GFSZ repealed, we can change 948.605 as follows:
Repeal 948.605 (2)(b)1r, amend 1m to read "A person who possesses the firearm in accordance with 18 USC 922 (q) (2) (B) (i), (ii), (iv), (v), (vi), or (vii)." (this would allow CCL holders to carry INSIDE of schools).
If we get the Federal GFSZ repealed, then repeal 948.605 in its entirety.
