I was getting ready to print off a address label for a parcel on eBay that I had sold & while in the process , this warning popped up, never seen anything like this before.

USPS routing through major hub in Chicago, Il is currently experiencing a rash of violent shootings. Since you are in Indiana,  perhaps the warning is a regional message from ebay.
