Ehhhh this is a not a good prank. Yes I don't like jerks on the Internet. I especially don't like egotistical, sexist, pigs who harass people on the internet.
But getting a SWAT team to kick down his door? I don't care about the guy, but what about the SWAT team? They have stuff to do, training to complete, their own lives to lead. They don't have time to get involved with pranks. This prank was inconsiderate to the police officers involved.
There's a reason calling Hoaxes in to law enforcement is a crime. It takes up their time, it diverts resources, it causes more additional, pointless paperwork, it wastes time and it's just not pleasant.
Fine, you don't like jerks on the internet, mute them. That's what I do. I MUTE them. I don't read their chat text, I don't respond to them. I ignore them. But I also don't get the police involved and waste everyone's time just because someone called someone I know bad names on the internet.
EDIT - and what about the cost to taxpayers? Deploying a SWAT team isn't cheap. You don't just roll up in your car to the house. You need to plan, to organize the equipment, get ambulances on standby, load ammo and pay for the fuel to drive a lot of vehicles there. You need to hire people to seal off the area around the scene, you need to get Police Department PR to deal with the press - calling in a SWAT team is NOT FUNNY, it's EXPENSIVE. I'm not saying it costs hundreds of thousands of dollars, but it probably did cost hundreds of dollars, if not thousands - taxpayer money that could have gone to better use.
This is what I hate about the internet - yes, Keen was an inconsiderate, sexist pig, and I don't care if he was pranked. But using up police resources and time and taxpayer money IS ALSO inconsiderate and wrong.
Bah - kids these days. They never THINK about stuff, they just assume they know everything. The Police and the SWAT team aren't there for you to use in your pranks. This is just stupid.
