One of the things that disturbs me here is that this guy took the time to dress up to make sure that everybody involved knew that he represented Christ. I don't know everything that happened here, but seeing what's available in this post it appears that the Rev. Lang took sides on this dispute.
I don't know what the cause was but it appears that he was not a buffer between the police and demonstrators but had actually chosen sides in this dispute. Of course sure I'm making a judgment with not knowing much of the story. I followed the link on the post and the story was not readily available. Maybe you can help me out here BB.
Okay I have an update here, the good Rev. was involving himself with the occupation Wall Street crowd in Seattle. This is total politics nothing about fighting for Christ. Apparently the Rev. Lang felt that he could depart the gospel to the member's of occupy Seattle during this riot. I may have agreed with Rev. Lang if he confined himself to the staging area of the protesters. The protesters had a small village, with tents and other amenities set up for what appeared to be an extended stay. This could very well have been a good environment for Rev. Lang to preach the gospel, but it appears he went far beyond that and involved himself in the protest.
