Mass killings in London, Portland, and Orlando over the last seven days (occurring at an increasing rate). We have categories for each type of attack:
- London: Homegrown Jihadi terrorist attack.
- Portland: Hate crime murders.
- Orlando: Lethal postal rage in the workplace.
If we examine each category by itself, it's hard to determine any underlying factors common to the attack of that type. Jihadi terrorism has lots of contributing factors.
