Just to clarify, "wiretap laws" only apply to an expectation of privacy. Say like on your private ground lines, or in your house. But if you are in a public place, it is totally legal to record. This has been argued many times by celebrities. I don't know the specific ruling. I do understand that SCOUS has ruled this.
So anything that can be seen or heard in public can be recorded
no its not papa, if it were this simple the subject would not have gotten to the highest court of the land...celebrities' argue because they were recorded and didn't want to be and the courts have ruled you are a celebrity and have no expectation of privacy. there are some states which as pointed out have singular permission and some states mandate both parties have to know and consent to the recording or it stops, immediately! if it doesn't you can and prob will be in a judicial proceeding.
