True objectivity is a rarety, especially in media. Example: chat forums, NPR (national public Radio), etc. I remember having covered this in English class in HS: a project where we evaluate news local news reports, and conclude that they often back a certain political stance.
I don't know who else to quote on terrorism except professor Cunningham who has written several books on the matter. You were right, I mixed the facts up a bit, the corrections (taken out of my notebooks) are as follows:
South Asia ranks #1 in the most LETHAL forms of terrorism
Latin America ranks #1 in the most FREQUENT amounts of Terrorism.
However we focus on the mid-east now in our media, mainly suicide bombings. However the largest number of suicide-bombings is in Sri Lanka.

That's right out of my notes, sorry about the earlier mix-up


PS I will edit my orriginal post by putting parenthesis next to cited facts about where I heard the info from.
