Congress is considering a law to make it a serious crime to send a SWAT team to someone's house by making a false report.

I don't think this will put an end to the practice of "swatting". It is too easy to make these false reports. Meanwhile, the practice is made easier by thug departments that use SWAT teams too readily. The lower the bar for sending the SWAT team to raid your house, the less someone needs to do to get them to send it.
