- the law will severely restrict law enforcers from using telephone / ambient wiretaps. Practically the use will be allowed only for mafia or drug related crimes. All the rest (murder, kidnapping, corruption and other white collar crimes) will be a no go. See the comments made by the very US Dept. of Justice a few weeks ago on the subject.
- the law will punish journalists / editor ho disclose acts that are now of public domain.
It is my understanding that Italian and US laws are very similar in that respect, now. It is prohibited and punished the dissemination of info of an ongoing investigation. At the end of the investigation, when the indictment charge is filed, all the acts therein contained are made public.
With the new law (god forbid), all those acts will be kept secret until the end of the trial. In Italy it mean 5 to 10 years, if not more
With that law in effect you'd know your neighbor is a rapist, or your local administrator is a thief, after 10 years...
