kimberly, what do you make of the fact that three attacks happened in the uk in just three months time and prime minister teresa may says they are not connected? what s going nont uk that there s this increase number of events? well, part of it is the number of militants who traveled from the uk, served with isis in iraq or syria or other parts of the middle east and have come back. they re also many other sympathizers within the british society that british security is tracking. so you have a collection of individuals like minded with the skills or the will to carry something out. but you also have this sort of virus spreading of people seeing these attacks and n. places like nice in france where more than 80 people were killed. they re seeing the simple tactics work.
