Also...is the drug dealer really complaining to police about getting beaten up...at a drug deal?
Does that sound strange to anyone else?
It might not be common but I don't think it's that rare. People call 911 when they think they didn't get the amount of drugs they paid for.

That is hilarious.
BBall is right. Criminals do stupid things.
Here is a true story that I can't tell you where it happened or how I came by the info but it is true.
Two men got into a fight started by this one guy over a bar seat. They take it outside where the guy that started the fight takes a decent beating and so runs to his car and proceeds to run over the guy he started the fight with and kills him.
Bleeding from the beating he took he goes to the hospital where they ask how his injuries occurred. he said he got into a motor vehicle accident in the next town over. The nurse tells him to go to that police station and report the accident because if they find the guy that he got in the accident with, his insurance company might be responsible for the bill.
So he goes to the police station, where they are already looking for him because someone reported his plates to the police and they ran them and found out that he fit the description of the man behind the wheel who murdered the bar patron. He goes in wanting to report a car accident and gives the cops his name and license plate number and says it occurred recently in the city and says it happened in front of the bar where he killed the guy.
Needless to say, they brought him into a room where within a few hours they had enough evidence against him that when he lawyered up, he was toast.
And you wonder why drug dealers call the police when they are beat up when drug deals go bad. Its simple. These people aren't too freaking bright.
