There's a lot to unpack here that you blurred together. To the first thing - if your tactic isn't working, pick a new tactic. Laying in the road, so far as I know, is not the only tactic available. I'll ask again - what "awareness" are you creating that wasn't already created by Castille's death, the subsequent events in Dallas, and non-stop media coverage? This isn't 1960, awareness is pretty easy to gain. What you are comparing these to are not in the same ballpark. This isn't thousands of people demonstrating, it's a small bunch trying to overcome their lack of numbers with degree of annoyance in tactics. I don't think it works that way and it certainly doesn't seem to be working.
