BBM-
Not necessarily, some just don't post or quit thanking those they agree with due to the mob mentality. I have received a few pms of thanks from posters not thanking or posting, afraid to raise the ire of the group. Sometimes it is difficult to speak out when you feel you are treated like the fringe minority. I don't even know what to think, because Wilson has not even been charged. So, I don't feel like he needs to be defended against an overzealous pro-guilt crowd, which is weird for me, because I usually argue for the defense.
However, I feel like a few posters are making some valid points questioning the handling of this case and Ferguson Police Department's handling of it, specifically. Some other posters question critically anything that shines doubt on the LE but are credulous of anything that makes LE's version seem believable. For example, lawyer X discredits someone we don't like, when the poster has no idea who lawyer X. If you google, lawyer X you find out he is a shyster, has ethical charges, or may have a conflict of interest.
I think one should be skeptical of everything at this point.
These cases to often become arguments and sides seemed to be formed. Life is not binary, so why should investigations be?
