This week we have seen scuffles at Racket Hall between the Gardai and protesters as 16 Asylum seekers, women and children tried to seek refuge. Phrases like 'Roscrea is Full, 'Plantation' and 'Scam' have been used by protesters. Why is it that many people have fallen for these slogans? 

David Robert Grimes, author of "The Irrational Ape, Why we Fall for Disinformation, Conspiracy Theories and Propaganda" tried to debunk protesters conspiracies.   Henry McKean sent us this report.
