This is kind of farfetched, but after all it's halfbakery not fullbakery, right?
Take a typical riot gear vest and with rows of sprayers under each arm attached to a "camelpak" style container pepperspray on on the back. The vest would have what is commonly called a "suicide switch" (a type of
mercury switch used as a detonator by suicide bombers, it's held vertical where the mercury can only touch one of the detonator's contacts, if they get shot and fall over, the mercury sloshes to the second contact when the switch goes horizontal and BOOM) concealed beneath its padding. Now instead of the switch detonating a bomb it releases the sprayers.
If the officer is overpowered by rioters and he falls over, in this moment of critical vulnerability a large cloud of pepperspray is released in an effort to keep the crowd away from him until he can regain his footing or his fellow officers can assist him. Of course, gas masks are a definite neccessity when using these suits.
Also, pepperspray could be substituted with CS gas or mustard gas if you live in a particularly spiteful country where you can get away with that sort of thing. Another nifty addition would be an ear-piercing alarm that goes off with the pepperspray to both ward off attackers and to alert other officers of their comrade's status.

//Riot gear that senses when user is in danger and releases pepperspray cloud// |

When I first read this I thought you meant this: |
|
| |
Rioter: Boo!
Pepperspray Vest: Pssssssssssss .... |
|
| |
It *is* a very funny mental image to imagine this riot gear system working when an officer has no gas mask. |

I think I like [ixnaum] version better now.. but that's just because I'm mean |

I have some advice: never, ever start an idea with this mantra. |
|

feh, it's like my first idea ever to not get fishboned to all hell, so stop raining on my parade already [Detly] >:| |
|

yes, + because it is a cloud. ...imagining accidental release in elevator. |
|

obviously, it would have to have a some sort of arming device or switch.. the last thing you want is for the stocker at the police station to throw these in the back of storage and fill 3/4 of the police department with pepperspray |

I always wondered why IRA suicide bombers used mercury
switches instead of
buttons. Thanks for explaining. |

These days, it would be trivial to use an IMU instead of a
mercury switch, so that it
could detect that the cop actually fell down, and not
trigger spuriously if a cop has
to deliberately lie down, jump, etc. |

(Back in 2005, the only consumer-level accelerometer I
know of was the Sudden
Motion Sensor in the PowerBook G4 (intended to park the
HDD heads if the laptop is
dropped, also used for lightsaber effects). The Nintendo
Wii came out in 2006, and
the entire Wiimote was the cheapest and most accessible
accelerometer for a while
after that. It didn't even include a gyroscope at first—that
was a later-released plug-in module, before being built in
even later. I imagine the PlayStation 3's SIXAXIS
controller (also 2006), which did include a gyroscope,
would have been used as a
cheap IMU too, if it was more easily interfaceable. |

Nowadays, IMUs cost pennies, and every phone includes
one. More relevantly,
devices like the Misfit Shine use them to detect bike
crashes and the like, and alert
responders. In the same vein, it would be extremely
feasible to use one in a pepper
spray vest, to detect falling over distinctly from other
sudden motions.) |

Could also work for drunks, inflating air bags
etc |
