This is why Del Carmen is perplexed about Wednesday's events.
He is a police consultant to the federal government and has trained agents for both the FBI and Homeland Security. He holds a doctorate degree in criminology and criminal justice.
He is also an associate dean and professor for the College of Liberal and Fine Art, specializing in Criminology, Criminal Justice, and Strategic Studies at Tarleton State University.
Del Carmen said ample resources are always available to Capitol Police and can't understand why they weren't deployed sooner or were in place earlier to establish a perimeter.
"There is a whole machinery in place that comes into play days before something like this," Del Carmen said. "We do advance research, social media sweeps, crowd assessment, and we get intel on the ground."
