Cops and Robbers - Concepts

pick a role...
Choose robber?  Tap a button to commit a crime, it will use your location and send out a signal with a radius based on the severity of the crime.  Flee the area, and make it outside the radius of your signal, or make sure you don't get caught by the time your radius shrinks to zero, and you'll score points for getting away with it...  when the ability to commit another crime is available, you will be notified.
Choose cop? you’ll receive an alert when you are within the radius of any robber's committed crime.  Get physically close enough to a robbers location to enable the “catch” button, tap it in time, and get points based on how sever their crime was, and how fast you caught them.  There is no time limit to how many crimes you can stop.  
Earn higher ranks as a Cop as you catch more and more robbers. 
Earn bigger reputation by committing increasingly larger crimes. 
Check the leader board to see how your rank compares to everyone (this would actually NOT show friends, as you'd probably want to keep your (cops or robber) identity a secret as long as you could) ;)


--- careful not to create REAL fights.... so, radius to signal cop/robber they are in range, cop needs to get closer to be able to “hit catch button” and robber needs to stay OUT of this closer range for a given amount of time based on the crime type, to be able to hit the “escape” button
 --- essentially i don’t want a game about fake crime/violence to create ACTUAL crime and violence, or to scare pedestrians who have no idea what is going on, OR to desensitize people to thinking that maybe an actual crime is taking place, or maybe it’s just my game.... 

-- variation High Five Me! (aka, only positive thoughts)
W\hen you are close enough to another player, your phone buzzes you have to go up to them and hi 5, (not really) but somehow scan an image on the phone to get it to count.  (like one of those square scan things) You can only high five the same person once per day.  Leaderboard of the most high fives?  
---- no risk or challenge or options for player... which makes this a weak “game” idea at the moment, but a fun thing to collect...
------- maybe for advertising, a “deal of the day” to local winners? or “deals “ of the day? 
Where a person would want a coupon, so they would hit the "high five me" button in the app, and it would send out a signal to all other people running the game, if they tap it (high five back) you both get the coupon (let's say for a free donut).  This could also work based on location, and through advertising in the area. 

I’m not sure about this one... I originally thought of it when I thought the situation would be fun when.... people were just going about their daily life, and then their phone buzzed... oh man, there’s a robbery that just took place... the "cop/player" looks around to see who might be trying to "play it cool", or trying to sneak away from his current location.  meanwhile, you tell your friends you need to be right back, as you run down the street to apprehend the person you suspect just committed the crime... you got close enough, so you phone enabled you to “catch” them... you can now confidently stroll back to your group of friends who are waiting for you to sit down at dinner :D  unfortunately, the whole experience i want to create could be troublesome if people take it too far.   

Either way, it's an idea/concept of an idea i had floating around that i wanted to jot down.  about people interacting with people in the form of a game. Might make people get along with each other a little better if we all could help each other out JUST a little bit... and I just think it would be fun to interject some childhood (cowboys and Indians) type fun into our daily life as busy "adults" ;)
