#Colorado: Police confirm an active shooter at #Boulder High School. A shelter-in-place order has been sent. Please avoid the area.

In a tweet just before 9 a.m., the Boulder Police Department said officers were responding to a report of an active shooter at Boulder High School

Schools are on lockdown, according to the Boulder Valley School District. Reports of the active shooter have not been confirmed by police.

Schools usually start late on Wednesdays, so students usually don’t report until 9.35am. Boulder Valley School District spokesman Randy Barber said the school is telling parents and students not to come to campus at this time.

A public information officer was on his way to the school, police said in a tweet.

Immediately after the shooting, many people expressed shock and sorrow at what had happened. Many of these people called for stricter gun control laws so similar incidents would never happen again. However, little action was taken by law enforcement and government officials in response to these public statements. Some of those who did take action were students who created a petition requesting that the governor suspend the shooter’s ability to purchase firearms. The shooter had threatened students with a gun before and had been expelled from school for it. This shows how easy it is for someone with a gun license to purchase ammunition in quantity without detection by law enforcement.

The shooter was also arrested after attempting to buy ammunition from an undercover officer. Authorities were able to catch him because he made arrangements through an acquaintance who had been arrested for selling firearms earlier that day. From there, authorities were able to identify the shooter and locate his weapon at his home. After this, the shooter pleaded guilty to attempted murder and was sentenced to 15 years in prison- a far shorter sentence than what he would’ve faced if he had successfully purchased ammunition from his acquaintance.
