It's a SCAM! A small fraction of your donation is used for the stated purposes. The OVERWHELMING percentage of your donation goes to the fundraisers. DO NOT PARTICIPATE IN THIS SCAM!
This positive review was posted in 2007, but do not stop reading here. Since this post, it's been established that OTC uses professional fundraising companies which keep over 90% of the money collected.
Also, research how many public safety people they have helped... I have yet to find any proof they have ever helped anyone.
Carefully research this group before donating.
