Uvalde School Shooting: Blood-Written 'LOL' Sparks Calls for Gun Law Changes.

The Uvalde school shooter used the blood of his victims to write “LOL” across a whiteboard inside a classroom at Robb Elementary School last year after he gunned down 19 students and two teachers, a Texas lawmaker revealed this week. The appalling detail was shared during a hearing on a bill that would raise the age to purchase semi-automatic rifles from 18 to 21. The shooter, Salvador Ramos, was 18 at the time of the shooting. The bill has faced opposition from Republicans, including Texas Gov. Greg Abbott.
