I now work with people with autism and other challenging behaviours, some of the client will do similar things to those in the article and will also attack members of the public, they dont have any entitlement to disabled badges either. We would however ensure that there is one person trained in physical intervention either side of any clients likely to cause a disturbance or a threat, never would we take them out alone, it seems to me that this lady needs to get the assistance of the local authority to see if she can get trained support workers to assist when taking this guy out in public, she clearly needs additional support. No I don't think it is a disabled badge that he needs, its more assistance from qualified and trained support workers.
