It makes sense there is a number of FBI agents because it hits at the heart of the USA economy. So, this is a major concern. I suppose there is a bit of an economic focus, but, if the police believe it is racial, then it says a lot about the bomber.
The diagram of the location of the bombs forms a right triangle, so the bomber had scoped out his/her targets. The targets don't appear random. Also there is a repeating number in the dates of the explosion. The number two.
They all have occurred in the month of March and the number 3 is understood, but, the day of the explosions are 02, 12 and now today 20. If the explosion in the FedEx facility was planned it would be 20, but, if the destination was the place the bomb was to explode it may or may not be 20 or 21. There were also two bombs on the 12th. Computers can run on a binomial basis, if that means anything. Usually, that is the numbers 0 and 1. I think a computer with AI might be able to synthesize a potential pattern and/or identity.
This is probably affiliated with the death of a police officer and/or the death of a African American. As an example:
January 26, 2018
7:40 a.m.update: A man (click here) who broke into a Central Austin home early Friday morning was killed by police after shooting at two officers who confronted him, authorities said.
When the suspect, described as a white man, entered the home in the 4500 block of Avenue G, the residents hid in a closet and called 911 around 3:40 a.m.
Officials said two officers arrived and announced themselves to the suspect, who then shot at the officers. One of the officers returned fire, killing the man at the scene, Assistant Chief of Police Troy Gay said....
There is also a map with this report, so this must be a methodology of the crime reporting community. That method may or may not be part of the strategy to terrify the community as well as kill what are believed to be innocent people. The backgrounds of the people targeted might prove a pattern as well.
One other thing about the numbers, is that when a date is reliable in producing violence, there will be higher fear quotients that can be affiliated with that. The public will begin to recognize the pattern and anticipate that explosion. That could be used as a public strategy to avoid packages on those days. Then with a pattern realized, the bomber could simply change the pattern and cause greater terror. I tend to think the dates are less important than the identity of the victims or intended victims.
I doubt any of this is new thinking for the police or FBI, but, why assume anything in an investigation.
I am sorry to hear this is happening to Austin. I have the greatest sympathies for the victims, intended victims, their families and friends. The city is a good city and the problems it faces are not very different than other cities.
If this is racially based it could be an effort greater than one person. Every American wants their cities to be safe and happy places for it's citizens. We all struggle with the racial problems the USA exhibits. It is not fair and it is not unique. Racial issues have been a problem throughout the world, otherwise, there would be no Robben Island. That is not an excuse, but, it is a reality.
I know the fear that lives in every African American man's heart and it effects their life. That is not a minor problem. Fear raises stress and can result in health problems. Fear of one being a target in society brings an entirely odd family dynamics. The USA needs to resolve it's racist problems, that includes ending the hate of White Supremacy.
I hope law enforcement will solve this swiftly, but, when it comes to these type of issues, it can be a longer timeline. I wish everyone safety and peace during this difficult time.
