Here is a scenerio for the braintrust here at CT. We had a big dispute about this yesterday at work. You have a caller who states someone in a van pointed a gun at him while driving on the highway. The caller stops at the nearest police station and gives his name, DOB and address and gives a written statement describing the vehicle/occupant who pointed a gun at him. You locate the vehicle and conduct a high risk stop. Do you frisk the vehicle or obtain a written consent for the vehicle? If you frisk how far can you go? Can you look in closed gym bags? Can you open containers? How about checking for hidden compartments? I forgot to mention the van contains mulitple occupants. Now change the caller to an "anonymous" tip. Do you take the same action? This is an actual scenerio we had to review. I will let you know what the guys did..
