Can you define Adeguate Security...?

There had been no previous attacks on or threats to cricketers in cricket?crazy Pakistan, and as such the organizers of the match series were confident that everything would go as planned, though some countries refused to play there for security reasons.
On security it mentions that it was being claimed by some quarters that Sri Lankan team had not been provided with adequate security. “What is adequate security? No security is adequate where terrorism is concerned. In a world where the Pentagon has come under a terror attack and well protected world leaders have perished at the hands of terrorists, there is always an element of risk in any kind of security arrangement.”
Even if there had been a security blanket in Lahore on Tuesday, terrorists would still have struck. “They are so fiendishly motivated and fanatically determined to cause bloodletting. There is hardly anything that a bunch of indoctrinated lunatics with a death wish is not capable of.” “Our cricketers are precious to us and we heaved a sight of relief when they escaped death and returned home safely. Now that the boys are back, we must put the unfortunate Lahore episode behind us.”
