Arwyp security staff utterly disgusting human beings

My daughter is in the pediatrics section and she's been here for 3 days now... My husband went downstairs to go smoke outside by the main entrance and when he came back upstairs he was visibly upset and completely disgusted by the inhumane actions of one of Arwyp's Security staff members. A homeless man who can barely walk and is using crutches to get around dropped a piece of paper and the security staff member from Arwyp told him to pick it up... As the man on crutches was trying to pick up the paper this security staff member picked up a huge brick/stone and actually physically threw this brick at the homeless man resulting in the man's leg being cut open! I am beyond horrified and disgusted that this is the type of staff that I have to entrust to keep my little girl safe in this hospital???!!!! My husband is in such a state because he had to witness such cruelty at a place that is supposed to promote a healing and caring environment! If it wasn't for the couple and my husband who helped this man, and who is demanding that Arwyp be responsible for this man's medical care, then I would have completely lost all my faith in humanity tonight... I honestly cannot believe you get such types of cruel and inhumane people who find joy in injuring and humiliating others that are less fortunate! That man should go to the police station and take this further, against the security staff as well as arwyp for being this neglectful and cruel. To add to this the security staff on duty at that moment even tried to defend the man who threw the brick (he was not on duty but was definitely wearing arwyps security uniform) and that CANNOT BE TOLERATED! REALLY ARWYP! TRULY DISGUSTING!!!!!!!!! (update: as I was typing this my husband went to check on this man and he says that the security staff currently on duty are still trying to defend the actions of this cruel man... Can really not believe this)
