You cannot let this be normal to you. You should look at this picture, learn the context, and be disgusted. Not hem and haw about it>
Edit I found the article, but somewhat disappointed that the context is one of the last comments with minimal engagement or up votes. Is there context available for this picture? I have not seen an article associated with it, just comments in the thread comparing ICE to Nazis. I can't think of many instances where zip tieing or handcuffing children is appropriate, but that is not the same as there never being such an instance.
I don't want to fall for rage bait, like with the "US Citizen Deported" headlines for citizen children going with their deported parents. Not that I am saying that is ok either, as any rush to deport where lawyers have not had time to be involved to ensure deported parents have all their options fully explored to ensure what is best for the children is a gross miscarriage of justice caused by a criminally understaffed immigration system, but misrepresenting what is happening by calling it deportation of US citizens doesn't help.
If this is in immigration court then no one should be cuffed outside of provenly dangerous individuals because it creates a subconscious bias of guilt, which is why it's not allowed in regular court. Also any cop that cannot maintain control of a single child under 10 without cuffs doesn't belong in physical law enforcement.
That being said, I can't say that physical restraints are never appropriate for both officer and detainee safety in any situation, because sometimes it most certainly is.
