"Authorities still have not found a motive for fires,"
There are only 3 possible motives for a fire like this:
1. Eco-terrorism
2. Insurance scam
3. Disgruntled employee
If it turns out that more than one person started this fire options 2 and 3 are unlikely, if it's more than 2 they are almost completely eliminated.
Lucky for our side that there is still an Urban Terrorism Joint Task Force still up and running. Didja knotice how fast the FBI and ATF were on the scene?
This is the same force that has been working out here in Oregon and Washington, and is responsible for the arrest of several arsonists in Oregon. Those boys are still in jail by the way. They were also involved with a wacko who was out trying to sabotage high tension lines here in Washington.
The ELF has always struck me as a very loosely defined outfit, and they make a lot of mistakes. If there's any evidence to be found, this group of people will find it.
