What is permissible police intrusion of an individual?

1. Level One of permissible police intrusion occurs where the police request information from an individual when "... there is some objective credible reason for that interference not necessarily indicative of criminal activity." People v. DeBour, supra at 223.

2. Level Two of permissible police intrusion of an individual occurs when there is "... a founded suspicion that criminal activity is afoot and permits a somewhat greater intrusion in that a policeman is entitled to interfere with a citizen to the extent necessary to gain explanatory information, but short of a forcible seizure. People v. DeBour, supra at 223.
