The Czech parliament toughens gun laws after the worst mass shooting in the country’s history

PRAGUE (AP) — The Czech Parliament has approved changes in the gun law that tighten requirements for owning a weapon following the worst mass killing in the nation’s history. After a green light from the lower house in January, the upper house followed suit on Wednesday. The legislation now must be signed by President Petr Pavel before becoming law. On Dec. 22,  a lone shooter killed 14 people and wounded dozens before killing himself at a university building in Prague. The assailant was a 24-year-old student who had a proclivity for firearms. Authorities said he had no criminal record and therefore didn’t attract the attention of authorities.
