1) The mother of 1 and 2, says up front that the FBI has been following her sons for 3+ years. See below.
2) 1 goes to Russia, supposedly was radicalized prior to his going.
3) Uncle goes live on TV, trying to distance himself from it all, but won't tell the press why he and his brother don't speak
4) Both kids allegedly bomb the Marathon, then are seen at car repair shops, playing bball on MIT campus, in classes, etc
5) Both kids are at a gas station that is robbed and end up shooting a campus security guy
6) Steal a car, tell the owner they bombed the marathon, let car own out and then get in shootout with cops
7) #1 is shot, #2 attempts to getaway and runs over brother, all the while throwing bombs out windows?
8) #2 manages to get away and elude 1000s of Bostons best, FBI and Homeland Security agents, sneaks out of their perimeter
9) #2 is found hiding in boat, is subsequently shot in the throat and will never speak.
Here is my take on these points. I think sometimes truth is stranger than fiction...
1 - S1 WAS being investigated by the FBI. A foreign country requested the FBI investigate him but he was later cleared after a background check. It is not clear why he was cleared but it appears somebody messed up.
2- That could be what happen, but we don't know at this point although there has been a lot of speculation floating around
3- We don't know what the family dynamic was, but it's easy to see how emotion can come into play here. Based on what we've seen sofar it sounds like neither of these guys had the brightest future ahead of them.
4- There is video that indicates they were the bombers, some of what has not been released to the public. I imagine that may be because this will be used as evidence, or may just be too sensitive to show to an already inflamed public. I don't believe either of them were currently enrolled in school, but again there has been so much info floating around on the interwebs its sometimes hard to get the facts straight. I did not hear they attended classes. I did see an interview with the mechanic who worked on S2s car and he mentioned S2 as very fidgety and thought maybe he was 'on drugs'.
5- I heard that they did in fact say they were the bombers. The driver got away when they stopped to get gas? I think it was a pretty confusing situation. I was listening to the scanner at the time this was happening and none of it sounded related to the bombing. I believe they ambushed the MIT police officer, killed him, and even stole a weapon. Sound pretty innocent to me.
6/7 - I heard an interview with the Watertown police chief where he said the suspects were throwing improvised grenades. They also recovered a pressure cooker bomb similar to those used in the marathon bombing. At one point S1 got out of the car and started approaching police. Sometime after S2 drove the car directly towards the police and ran over his brother. This may have actually been what killed S1.
8 - S2 may have been in that boat all day. It was just outside the search perimeter. Boston is a big town, and Watertown is a big suburb. I think he was able to elude police so long because he didn't move much.
9 - I read that article posted on Yahoo. It wasn't very specific, but it does sound like he'll live. Unless he has no hands or eyes I think they will still be able to get info out of him.
