There's a lot of local Flock maps out there. You can also submit your own.
For those who are more inclined to direct protest, you can spraypaint the lenses and/or the solar panels. If you dont want to get caught with spraypaint, use nutella or peanut butter. Its sticky and easily spreadable. Not that I would ever recommend vandalization.
Sure, the EFF and ACLU are going the legal route. That's all they can do.
