Most fearsome terrorist attack...

Just thought of this for don't know what reason.

What if , a terrorist has this plan...

1) Plan a food festival, and advertise throughout the country so a lot of people will come.
2) Put some laxative in the food...
3) Place several cleaning signs in toilets around the place.
4) While the masses run for the toilets and creates a huge commotion, announce that a bomb is detected.
5) ...watch people struggle between the 2 pronged attack, choosing between the toilet and escaping the bomb.
