1987 chp front bumper holes?

[bullitt2001]

I just recently bought a 87 chp mustang. I am now having it painted black. I noticed on the front passenger side front bumper it looks like someone drilled a bunch of holes in it. I was wondering if this is what California highway patrol did?? I was looking on this site and saw another chp that had the same exact holes.. Please help me with this because I was thinking of having them filled in if it wasnt done by chp. Thanks
