Sen. John Cornyn (R-Texas) defended police officers and law enforcement agencies after it was revealed they waited over an hour outside Robb Elementary School in Uvalde, Texas during Tuesday’s mass shooting.

Cornyn said blaming the first responders after the complex incident is “distracting and unfair.”

“The second-guessing and finger-pointing among state and local law enforcement is destructive, distracting, and unfair,” he tweeted Saturday.

Officers are being criticized amid reports they waited outside the school for more than 70 minutes as suspected gunman Salvador Ramos continued his rampage, ultimately killing 19 students and two teachers.

In a second tweet, the Texas lawmaker defended the officers’ “split-second decisions” and said it was “easy to criticize” following the tense moment.

“Complex scenarios require split-second decisions. Easy to criticize with 20-20 hindsight,” he added.

“There will be plenty of time to sort this out later. Focus now should be on [thorough] investigation and lessons learned to prevent future tragedies, not finger pointing,” he said in a third tweet.

SCHOOL SHOOTING PROTOCOLS CHANGED AFTER COLUMBINE TO AN ‘EVERY SECOND COUNTS’ APPROACH: EXPERTS

Scrutiny over the hour-plus wait by nearly 20 officers outside the school was renewed after it was learned an active shooter drill from two months before Tuesday’s tragedy instructed first responders to “stop the killing” and that the “officer’s first priority is to move in and confront the attacker.”

In yet another tweet, Cornyn said the officers should still face an investigation and potentially be penalized once investigators “nail down facts.”
