I think even if the law was changed unless it was constantly being tested your just going to get self censorship, editors will just keep dropping anything 'controversial'.

Unless you get high profile journalists being held, or someone like Amnesty international making a big thing about a journalists treatment it will just continue same as before.

The set up is similar to communist countries where much like the party infiltrates every part of the country here. i agree with the comments here about why somebody would allow things to be published ontheir relatives etc.
