What’s stopping action on gun control in the United States?

 

Demands grow for tougher laws after 19 children and two teachers killed in Texas school shooting.

Nineteen children and two teachers were killed in a mass shooting at an elementary school in the town of Uvalde, Texas on Tuesday.

Police say the 18-year-old gunman sent chilling messages online before the attack, and entered the school despite being confronted by a security guard.

Grief is turning to anger, as Americans once again demand tougher gun control laws.
