From the article:
"The Czech Republic already has some of the most lenient gun policies in Europe. It's home to about 800,000 registered firearms and 300,000 people with gun licenses. Obtaining a weapon is relatively easy: Residents must be 21, pass a gun knowledge check and have no criminal record. By law, Czechs can use their weapons to protect their property or when in danger, although they need to prove they faced a real threat.
I would guess that universal background checks here are OK then??? Oh wait also a test on gun knowledge and 21 to buy a gun. Aren't these lambasted all the time when proposed???
