first i would like to say that my english isn't perfect - so i apologize for it, i hope you guys will take it in consideration and as i try to talk in your language (most of you) try to understand it :-p
I like this concept of Herd behavior analysis, my hypotheses, the one who come first is encourage a weak team with more effective. Like at school when there is a fight and friend of one child come for help!
On the video there is also guys who leave the t-shirt (hum) probably for showing "muscle" and "force", like a warning.
"i come to help, watch the skills i have"
- So they see as weaker the team
- They come as Helper
- Need to show muscles for warning
nervousness and compassion?
