Step 1: get rid of all guns (it's that easy!)
Step 2: give everyone swords and other medieval weapons.
OK, now heres why: Most current gun control laws are in place because too many stupid people have guns, right? Kids seem to be constantly shooting themselves and rednecks never think there gun is loaded. Sooooo... by making it so that the most advanced weapon would be the cross bow these idiots would not possibly be able to kill themselves. Unless they were to fall on there blade, in which case it would have happened anyway if they had been carrying a kitchen knife or, say, a Nobel peace prize. Also, another problem with guns is that everyone can use one, any street punk, psycho or high school student. But swords require special training, sure your average punk could still sneak up and ax someone in the back, but muggings would go down because while everyone would have a sword, not everyone would be skilled and classes cost money, so the more money you have to protect, the better lessons you could afford. This means that your normal broke-assed crook may get his hands on a long sword, but only someone of middle or upper class would really be able to use it properly. Also the whole world be like one big AD&D game! All we would need is for elves goblins and orcs to reappear on earth. I plan to be a figher-mage with a str. stat of 17, Int. 18, Wis. 15, and 17 charisma. I will carry a +2 sword and be named Zath. I plan to lead a quest to explore the caverns of Kraige, it is rumored to be home to many un-dead creatures but the sword of Pelonore was lost deep inside it and with that weapon I can cast the spell of holy flare. There should also be a good deal of gold and gems in the cavern, anyone interested should meet me at Draks Tavern in the town of Shire. I will need a Wizard of at least level 8, a warrior who speaks orcish and a priest who has mastered the spell of turn un-dead. Once we have a party of at least seven warriors we will head out.
And that's how I plan to solve the problem of gun control. So who's with me?!?! I urge you all to print out this proposal and send it too your local congress man... and then find a safe place to hide when he sends out his goons to rough you up.
