"I knew you were trouble when you walked in," is probably what Taylor Swift said to the guy at her Pittsburgh concert on Saturday who was holding up a sign that read, 'Taylor Swift is with Satan.'

Not only was Joseph Jackson holding up a creepy sign, but he also made some pretty threatening statements on Facebook. According to the Pittsburgh CBS affiliate KDKA, Jackson posted, "Taylor Swift is Satan and that 6,000 years is six days and death comes on the sixth day, so Taylor Swift is in danger." Yeah, we'd say that's enough to get this guy arrested...

Jackson was searched after being escorted out of the concert where he was fortunately found to not have any weapons on his person. According to KDKA's sources, the pop star's team is extremely proactive in monitoring threats against T. Swizzle made on Facebook, Twitter and other social media sites. They found Jackson's posts and sent them to the Pittsburgh police.

Our advice to all of Taylor's haters would be to internalize that hatred and never post that shiz online. Especially if you plan on going to one of her concerts with a sign that reads like a line out of the Book of Revelations.

We're just glad this guy was caught before he could hurt anyone!
