Russow said that he's seen more police officers try their hand at it.
"I have, especially on the local shows. I know a lot of guys who train. It's like a hobby. It gives them something to do," he said.
"A lot of people like to compete and set goals and things like that, so I think it's great."
Aside from fighting, Russow said that MMA training can be very beneficial for all officers.
"There are more guys who just do it to keep in shape than are actually out there fighting on the local shows," he said.
At his gym in Bloomington, Ill., he said there are about eight or nine officers in a class.
"I think it's great. It keeps people in shape and they are learning moves that actually do -- especially with jiu-jitsu -- help you when you're out there on the streets."
Fighting at Home
For his Jan. 26 fight against Jordan, Russow was able to take the short drive to the Hard Rock Hotel in downtown Chicago a few days before the fight as he prepared.
Having a fight booked in the same place where he works and lives is a huge plus.
"I love it. It's the simple fact that I don't have to fly, go out of town. I don't have to provide plane tickets for my coaches," he said. "In that aspect it saves money, and then just being in the comfort of your home.
"The fact that all of your friends and family come and watch you fight, it's really exciting. I've been blessed to be able to fight in the United Center twice."
Russow was disappointed he wasn't able to win in front of the home crowd, but said that it hasn't tarnished his love of what he does in the cage when he isn't out patrolling the streets of Chicago.
"To me, it's better than a side-job I'd be doing anyway -- doing security somewhere, he said. "So at least I get to do what I love, train and fight and still make pretty good money."
