I saw that vid clip on youtube... that is horrifying that they would do that to you. Hope they had to answer in court to a judge on that one. They had no reason why they should have even touched you... security is mainly to over see and report events that taken place not assault people. Guess they are not too bright. From what I Am seeing in vid clip is bully tactics and abuse of authory (they think they have). Oh, I didn't realize at the time watching that vid clip that was you. All I can say is you are brave.
