My question involves criminal law for the state of: Illinois
In the state of Illinois, it is illegal to record a telephone conversation without permission or telling the other individual that you are recording the telephone conversation. However, in the state of Illinois, it would appear that an individual can use text messages that occur over telephone communication networks as a form of evidence against a defendant. As such, I am asking if it is illegal for a plaintiff to use the text messages as evidence without informing the defendant that he or she is recording the text messages. As I understand, some cellphones allow an individual to observe text messages but delete them after they are read. As such, I am considering that it is illegal for a plaintiff to use text messages against a defendant without the prior consent of the defendant or telling the defendant that he or she will have his or her text messages recorded and kept.
Has there been any legal discussion about this in Illinois?
Has there been any legal discussion about this in the U.S.A.?
Is it illegal for the plaintiff to use text message evidence that occurs over a telephone network against the defendant?
If not, why not?
What rulings allow such an evidential procedure to be legal or illegal in Illinois?
In Illinois, are the police allowed to, without my permissions, look at the cellphone text messages I sent to someone else's cellphone on that person's cellphone?
