john bussey, associate editor. as it turned out is on holiday in spain. your timing is impeccable. a horrifying scene there in las ramblas. >> yeah, i'm not in barcelona, shep. i'm in the north of spain. this is the time of year when tourists really do pack this country. barcelona is a particularly attractive destination. it's crowded not just with european travelers but with a lot of spanish. where i am, people -- this is resonating throughout spain. because it's reminding people of this problem in europe. london, france, germany all experiencing this type of attack. it reminds spaniards of 2004 when 191 people were killed in what was at the time the worst attack in europe in the post war era when a splinter group of al-quaida as you recall bombed the madrid subway system. >> shepard: now this. in the heart of the tourist season, absolutely peak season there, crowded with tourists. you would guess that there will be people from all over the world in one way or another involved in this. that just makes the isis propaganda spread further. >> that's right. y
