Previously a suspect was arrested in St. Louis charged with making
threats against 6 Jewish institutions in an effort tho threaten a former
girl friend.
The recent arrest is of a 19 year old American-Israeli man. He used
software to spoof the location of his phone(s). He made the threats
from Israel where he was arrested.
Not only have these hoaxes distressed people and raised the general
level of fear, they have led to money being spent on additional security
by some institutions. The WWII British campaign - Keep Calm and Carry
On - has never been more needed.
