What is a "hot zone"? People obstructing traffic and breaking a few windows merits recording the location of every cell phone (basically every person over the age of 10) for an extended period of time? That's textbook "unnecessary dragnet surveillance".
EDIT: How do you separate out:
1. People in the streets participating in marches. (maybe articuable suspicion)
2. People in the streets not participating in marches. (ipso facto no articuable suspicion)
3. People in their homes with their cell phones on. (ipso facto no articuable suspicion)
