"Obviously, you can't think like a terrorist thinks," Tony Myers, VP and COO of ETMC EMS, said. "Being in a rural area, we don't think so, but you never know. But also, we cover areas in Houston, Dallas, and our vehicles are all over the North and East Texas, so there's always the possibility."
Trinity Mother Frances says its EMT's are also on alert.
