Police said Saturday they had arrested 142 people in a two-day anti-terrorism security sweep around Milan prompted by the bombings two days earlier in London.

Excellent response. This activity would cause any activated terrorist to pause and take a double look - even to the point of calling off an operation if they feared they might be monitored.

Setting placemark and heading to bed. See you folks tomorrow.

Clyde says WOOF. That's dog for goodnight.

OPINION - SPECULATION: I agree.

We must remember though (and I know you do); that they will
probably regroup/recruit and do it somewhere else.

Yep, jihad -- another day.

...even to the point of calling off an operation if they feared they might be monitored.

I feel they likely have so embedded themselves in daily life in various and assundry locations they are "taken for granted" as part of the typical daily grind. If the locations they are planning to use are intertwined along that route, who's to be the wiser if they do or do not pull off their attacks? Packages or bags left under bus seats or on benches or ledges...even fast food bags could be lethal if packed with incendiary devices (besides the food).

Of course cost is prohibitive for preventive equipment, but the potential loss of human life has great cost as well.
