Forum Post: A simple FICTIONAL book idea...

I should start by saying, this idea im sharing is from a book im writing. The book is a work of fiction and in no way am I suggesting that anyone try this. Anyway... In my book there is a protest going on, baring a strong resemblance to OWS. They decide to shut down roads of their choosing by renting tons of cars and or sacrificing the use of their own cars and simply parking them in the middle of the street forming massive car barricades and just abandoning them. Those cars legally would have to be removed by a tow truck, the police couldnt just destroy them. It would take alot of their money and time... to clean up the barricade... and then when its clear... the protesters just starting filling it up again with more cars. The protesters do it in the middle of the night so there is less police intervention during the actual parking of the cars. I also dont believe the protesters could be arrested as it is just a parking violation. I wanted to mention this idea from a FICTIONAL book im writing... and I wanted some feedback. I really have to nail it home im not asking anyone to try this... it could be dangerous... it is simply an idea in my book.
