Crime Scene: The Texas Killing Fields - Netflix viewers express anger at police after watching series

It was the eighth mass shooting this year, according to the Everytown gun control group. It comes 10 days after another 18-year-old murdered 10 African Americans at a supermarket in New York.

A distraught President Joe Biden vowed to overcome the US gun lobby and find a way to tighten gun ownership laws. 'Don't tell me we can't have an impact on this carnage, he said."

Pope Francis said he was "heartbroken" by the shooting, and called for greater controls on weapons. "It is time to say 'enough' to the indiscriminate trafficking of weapons," he said.

Guns of all kinds, especially high-powered assault rifles and semi-automatic pistols are cheaper and more widely available than ever across the United States. The right to keep and bear arms is protected by the Second Amendment to the US Constitution.

When the subject of gun control was raised in the US Senate post the Texas shooting, Senator Ted Cruz promptly pushed back saying that an attack on constitutional gun rights "is not effective in stopping these sort of crimes."

The debate during the weekend, when Texas hosts the annual convention of the National Rifle Association. The NRA is the country's leading pro-gun lobby. Scheduled to speak there are former president Donald Trump, Senator Cruz and other prominent Republicans.
