In my area there are many Muslim women wearing hijab as well as Muslim men that come into local stores and buy up as much baby formula as they can. They usually travel in pairs and there is around 10 of them that come in. All they buy is baby formula and its different kinds. Instead of just one kind of formula which is what you give your child. You dont give your child 3 different kinds of formula. I have no idea what they are doing with the formula. All I know is that it probably is not good. They usually park far out in parking lots of the stores so cameras cant see their license plates. Once I saw one that had the trunk open and they must of had over 100 cans of baby formula. They usually come into each store 5 to 6 times a week to buy baby formula. That is the only item they ever purchase. I have heard that baby formula can be cut with drugs to make it look like there is more. I am not sure if this is what they are doing or not. But their activity is very suspicious and I have found that this is not an uncommon thing. I even found this article about a group of arabs that were put on trial for funding terrorism by selling stock piles of formula. Also this story tells of Arabs stealing formula and selling it to local convince stores.
The Christian Science Monitor even had an article about baby formula funding terrorism. The New York Post reports 2 Muslim men were put on trial for selling baby formula on the black market and not reporting it to the IRS.
Here is a very detailed article about this entitled "Stolen Baby Formula Funding Terrorism. Where’s the Outrage?" In 2005 the FBI even said that Baby Formula was being used to finance terrorism.

Considering all this it is amazing to me I have seen virtual no coverage of this. Nor any real investigation into this. If anyone has any personal stories of this type of activity in their area please contact me. Further my question is what is a concerned citizen like me or anyone else supposed to do when we see this type of suspicious activity? How does one get the attention of Homeland Security or the FBI on this subject?
