They want it banned because people were sharing information on social media and they feel under threat.
"Their private domestic lives, home addresses and members of family have been referred to in a way not connected to the duty of which that member was carrying out."
Seems the real ban is that Identifying a Garda's name and home address on social media. Sounds like they are using this as a way to avoid been held accountable for things they do on duty which gets recorded. Trustworthy bunch they are and all.

Can't see how this would be enforced without infringing on our fantastic laws with regards photographic freedoms. I hope this falls on it's face.
