How easy is it to get guns in America? We walked into a gun shop (sandwiched between a strip club and a dive bar) as foreign nationals who'd never so much as seen a gun before, paid $50 and were shooting within 20 minutes.
The shop offered a range of range accessories (such as Osama Bin Laden/"Jihad Muslim"/Michael Moore range targets) and sold guns to the public, ranging from simple revolvers ($250-ish) to Uzi submachine guns ($399) and M16 assault rifles ($1099).
Why go shoot guns? Because it's highly illegal in the UK and therefore fun.
