AITAH: Am I the A**hole Here?

[Giantone]

True story , happen at the Monmouth Mall in NJ. My sister who is handicapped had taken her car to the shop and had my Mom's car. Went into the parking garage at MM and the "security detail" met her when she came out of the Mall into the parking garage,she has the tags on her car but my Mom does not and she forgot. The Mall Security detail called the Police on her to issue a summons , when they arrived my sister was outside the car and the Police saw her , told her to have a nice day and let her go ,not before tearing into Mall security,noting that once they knew of her handicap should have let it go.
