Wow this was really interesting. The fact that simple household cleaners will get rid of all the evidence in the area. If all the blood is gone they will have to resort to finding hairs that belong to the killer of other physical evidence like skin particals. The killer that uses it will surly have a clean getaway! :-)

I found this article really intriguing. First of all, I thought it was so cool that you can get rid of all the evidence (blood, fingerprints, footprints, etc.) by this chemical called "oxy". It is not like I am going to kill someone and use it to get rid of the stains, I am just saying it is pretty cool. Another think I thought was cool was that they use just oxygen and water to make it. Well, at least the police found something to detect the chemical, and remember I won't go out and kill someone!

This is very interesting, on the plus side, the new cleaning products really work, but the new ones also let the criminals get away before anyone could do enough testing in order for the police to figure out if there was any blood at the scene at all. But, because of this arcticle, there might be some new annoying ads for the oxy cleaners, hopefully, none of the criminals will be watching TV. It's kind of interesting that this is good and bad, like the lesson Ms. Ghazharian gave us on the goods and bads of technology. It is amazing that something as simple as a cleaning product could have that many chemicals and other "non-natural" substances in it.

It is cool that these products can cover up traces but it is also frightening how easily criminals can get away with violent crimes, just by a common household cleaner.
