The ISI does not STOP attacksCongratulations to KPK police and RIP to innocent.
Maybe we should disband ISI and CTD since they are clearly bloody useless.
It uses human and signal intelligence among other means to find out about potential threats.
Here's how it works
The ISI hears that some guy is on his way from Afghanistan out to kill people, they know who is handlng it and what possible timeframe we are looking it.
They don't know which entry they will use, what exact time and day and what route will they take to get to their target.
That information is sent to the ctd, police and other LE. These LE's then try to decide where to use their VERY limited resources to allocate.l check points and carry out extra security at what are potentially hundreds of targets and hundreds of routes to each target
Based on pure probability, someone always sneaks through
