I support the President and feel Dems and the ACLU go to far in their hysteria. I DO HOWEVER, have concerns about this, and many other creeping creepy law enforcement tools. EVEN if they get this, as others have said, it will be used AFTER the fact. How exactly would this make anyone safer? How safe is safe enough? I hope no one tells me if it only saves one life. Heck, we could save a lot of lives if no one drove over 5 miles an hour.
I sometimes search for disturbing words written by libs/Muslims, and then post the info on other sites (it's called opposition research, IIRC). There are perfectly harmless activities that appear suspicious to the Feds. Sometimes, I have sent the info to the Feds, if it was a threat against the US or the authorities. I told the Pittsburgh Police about threats to shut down a recruitment office, and they showed up in force. I felt good about that. This idea though, gives me the willies.
