I like "GTA- Vice City" 's method of gun control: All guns would float in a shiny bubble at the front of the security gate but if you were smart enough to "Rocket-jump" in front of the gate , or stack cars to flip over them like some sort of explosive ramp as "San Andreas" did, or retro-fit your car to float over the water "Cuban style" with codes or over-encumber yourself with the too many weapons "DOOM" code, or get into a poorly guarded airplane and do a "Liberty City did 9/11".
Whoa, maybe "Jack_Thompson" is correct. Maybe video games have rotted my brain.
