Emergency crews have another active shooter training exercise scheduled for May 21. Residents are being told not to be concerned when they see a “large contingency of police, SWAT vehicles and ambulances” in the area.

“If something ever did happen like this, we’d be prepared and ready to handle what we need to handle,” said Johnson.

Southlake officials say they go through the drills to assess their capabilities and readiness to deal with an emergency situation.
