Vienna Convention violated: diplomatic bag opened
Media Coverage: UK television and national newspapers all covered story. Prime Minister's anger broadcast on radio and TV.
Prime Minister:

“It is a breach of the principle of state immunity and the principles underlying the Vienna Convention on diplomatic relations,” Mr Cameron said.
“It’s an extremely serious action that took place.”
“We asked the Spanish authorities to investigate urgently and they have done that. We’ve now received an explanation from the Spanish. We’re reassured this will not happen again but let me be absolutely clear — we will always stand up for the rights of people in Gibraltar and for the sovereignty of Gibraltar.”

Hague Convention on Child Abduction violated: 4-year-old girl abducted
Media Coverage: UK television and national newspapers contacted but total news blackout even though known international elements were involved including a foreign authority dubbed "the kidnapping office" by an international-child-abduction-conference speaker.
Prime Minister: Cameron does nothing against perpetrators but does force anonymity on my whole family.

The conclusions are straight forward: "Great" Britain's leader considers a diplomat's bag more important than child abduction; the Prime Minister will not stand up for the rights of people in Britain.
