well, as far as israel is concerned, the choice is between a palestinian inconvenince, and terror attacks. no one likes to cheak every single car in those cheakpoints, and nobody likes to detain palestinians, BUT since expirience has showed us that even if dana is peaceful, that doesnt mean that the car behind her might be as peaceful.

palestinian terrorists has transfered weapons and bombs thru civilian cars, thru ambulances, thru children and a few times even dressed up as a pregnant women... due to these actions, the idf had to put up the roadblocks and cheakpoints.

if the choice will remain between checkpoints and israeli civilians dying, i'll take the first one any given time.
