MILWAUKEE - Take a drive on South 6th Street in Milwaukee and you won't need a radar gun to know people drive fast.

"I got my own radar gun," said Leo Kolacinski.

But that doesn’t matter to Kolacinski. He lives on the 5200 block of South 6th Street where he uses that radar gun on a daily basis.

"It works great, it works great," he said.

We first met Leo and his radar gun about a year ago on this 30 mile an hour stretch. We went back to find he keeps clocking speeders.

"There's a 50, that guy's going 51," said Kolacinski.

And he's writing them down on his log book.

"There's a 45, 46, some 50's here," commented TODAY'S TMJ4's Jay Olstad.

It's this constant record that has Leo's mind constantly worried about his grandson's safety.

"If he's out there trying to get the paper or the mail, he'll get hit," he said.

The last time we were here, we brought our Speedbusters gun. But this time, we brought a little more fire power.

Milwaukee Police officer Gregg Duran pulled over a handful of people, all of them going 14 to 15 miles over.

"More people died in crashes not wearing seat belts than in homicides in the United States," Duran told the driver.

It's a warning after the driver wasn't wearing his seat belt and didn't have his license on him.

That's why Duran pulled out a new print scanner just to make sure the driver was who he said he was. It's new technology for MPD.

"I got to take your finger print here," he told the driver.

Leo Kolacinski wants people to know if you speed past his house, there may be more than just him and his radar gun.

"You might get caught and you might not. But they're out there," he said.
