It's suspicious and fear propaganda because they called it a "Mass Casualty Incident" before they even reported about anybody getting shot.

To me it looks like they were withholding information to make it seem scarier. I read 6 articles that were updated 2 hours after your post and none of them said 3 people were shot. So someone knew what was happening because you heard that info but they stopped spreading it around so they could have their fear porn.

It was a real shooting.. 3 people all shot in the leg and there was an altercation between 2 groups which caused the shooting so it was not some random person trying to go shoot up kennywood

it looks like it was some possible gang members arguing and shooting poorly.

But the media was doing their best to spread the fear porn. 2 hours after OP posted this they were already calling it a mass causality to spread the fear. But they had to have know the real story because OP had already posted correct details about 3 people getting shot before them.

Likely fake because if the shooting was "real" then the fake news would be talking about it at least until the shooter's identity was discovered.
