But what happens, when the suspects are getting away outside of your home?
Robert Wallace, 81, faces attempted murder charges, among others, for shooting at two men who were trying to steal a flatbed trailer from his Wheat Ridge driveway in February.
Wheat Ridge Police say Wallace shot one of the men in the head, causing serious injuries.
Friday, months after the incident, federal agents arrested Damacio Torres-Ochoa, 32, in Boulder, while Wheat Ridge detectives arrested Alvaro Cordona-Deloera, 28, in a Westminster park, in connection with the case.
The suspected trailer thieves went months without facing charges, while a metropolitan auto theft task force investigated whether they were a part of a larger theft ring.
Investigators decided not to pursue charges, so the case went back to the Wheat Ridge Police Department.
"We did not want to jeopardize that investigation," said Wheat Ridge Police Department Public Information Officer Lisa Stigall.
Wheat Ridge investigators moved quickly to arrest the two Friday.
But U.S. Immigration and Customs Enforcement agents found Torres-Ochoa first. They arrested him on an immigration violation at his Boulder workplace, Stigall said.
Wheat Ridge detectives picked up Cordona-Deloroa about three hours later in Westminster.
Both he and Cordona-Deloroa are being held on a $100,000 bond and will appear in Jefferson County court Monday morning.
Wallace would not comment about the pair's arrest Saturday, only saying he was thankful for an outpouring of support from community members after news of his situation reached various media outlets.
"I've had people come by and stick a $20 bill out to me," Wallace said. "And I told them there's no fund, there's nothing yet."
Police say Wallace heard a commotion outside of his home on Sheridan Boulevard on February 24.
Wallace admitted to firing two shots at the suspects from outside his home.
But police say his admission did not come until two days after he called 911 to report the trailer theft.
Jefferson County's District Attorney has charged Wallace with attempted murder.
Wheat Ridge Police say Wallace never reported he felt in fear of his life during the theft, and say
Colorado's "Make My Day" law does not apply outside of your home.
"If you read that law," Stigall said, "It specifically talks about inside your dwelling, inside your home. Not in your front yard, not on the street."
Investigators eventually arrested Wallace, and he now faces a September 7 court date for his actions.
