Now come on, G, you are surely not saying that you can envisage any situation where a family can justifiably be beaten up by private security guards ...
No of course not Janet. From what I see a lot of what goes on is an assault and appalling and should be dealt with by the authority's. But I have been in situations where if you hadn't seen the whole incident you would be quite rightly outraged.
One incident nearly cost me my job and saved the life of my Police dog because it could have been put down. It could even have landed me in jail! Luckily for me as well as the person who only saw the last 50% of the incident there was one person who saw the whole of it, made a statement and saved my bacon! So with that experience in mind I will always err on caution when viewing only part of an incident.
If you break down what you see the assault on the woman seems clear, the rest must depend on what happened prior to the filming taking place.
If it turns out that the whole thing was completely unprovoked assault by the guards then they deserve to be sent to prison and I agree.
