My wife and I stopped at the grocery store yesterday . We have handicapped placards for both of our vehicles because of her back issues . I dropped her at the front door and went and parked in a Handicapped spot because she always walks back to the vehicle regardless . After we got through we came out and found my left rear tire flat . As I was changing the tire I noticed what appeared to be a cut in the sidewall . It looked suspiciously like a knife blade puncture . I'm curious to whether somebody thought I was jacking a Handicapped spot and decided to teach me a lesson . I would have rathered they just confront me and let me explain the situation . My wife said maybe they didn't like my big American Flag on my tailgate . No telling ..

Any security cameras at the store that would show the Handicapped Parking Space?

Here in the Seattle area it's clearly understood that if you have any conservative bumper stickers or NRA stickers you're open game for vandalism to your vehicle. It's expected and has been for years.

Take the suspect tire to your tire service place. They can tell you what happened. If its a deliberate act, call the cops.
