Perhaps the use of writing and the ability to read (both could be argued as being classified as technologies) are being misused by these rioters as well. We should limit the ability for individuals to have access to these dangerous technologies so that we may protect the masses. Hmm. Dark ages anyone?
Thing about the gun nuts is - to an extent they are right in that the technology isn't solely at fault - it takes a person to kill another person. With that said, guns are explicitly made to kill, and so limiting availability of certain types of guns is OK in my book because of this.
Likewise regarding your statements about a time delay and police monitoring - I ask this - should we allow governments to filter what we see? Yeah sure to a certain extent this happens now in various ways but what happens if an oppressive regime has total control over communication? What then?
