“Those who sign the petition are now on an arrest list.”
Have you seen such a list? Didn’t think so.
Any on-line petition is being recorded in a database. And any database kept on-line is accessible. The government has a Total Informational Awareness program. They can get all the information they want whenever they want. I have a 30 year career in Information systems, and I know how easy it is to get information kept on-line.
Your argument is lame and naive. A straw man argument at best.
Like gun registration, they don't have to call a gun-registration list a gun seizure list until they decide to use it as one.
