A police officer had a perfect hiding place

There, standing by the shoulder, was a ten-year-old boy holding a big handmade sign that read:
“RADAR TRAP AHEAD.”

The officer sighed. “Well, that explains that.”

But it gets better.

Another hundred yards beyond his hiding spot stood another kid — this one with a sign that said:
“TIPS.”

And beside him?
A bucket full of cash and loose change.
