Why was she free to begin with?

On Monday, vigilant policemen in the Old City of Jerusalem caught a 24-year-old Arab woman who was planning to commit a terror attack, according to Israeli police.

The woman, a [so-called] “Palestinian” Authority resident, raised the suspicion of policemen stationed in the city. They checked her bag and found a large knife.

The woman said she was there to stab police officers.

This wasn’t the woman’s first time. In fact, she had been previously caught three times with a knife.

In her previous attempts, she was caught at a Hebron checkpoint where she said she was planning to stab security personnel.
