If you see the Laramie County SWAT team deployed at East High School today, don't worry.

It's only a drill.

That's according to a post on the Cheyenne Police Department Facebook page:

''The Laramie County SWAT team will be conducting a training exercise today at East High School. Please be aware that the training is going on. We'd make a SWAT joke here, but the SWAT team doesn't joke."
