Besides doing a radio show, writing a regular column in El Universal and being a frequent guest on TV he has done recently a rather complete investigation on the infiltration of the Colombian warring factions across the Venezuelan borders. Mainly the FARC and the ELN apparently more than tolerated by the Venezuelan army, with sometimes the AUC pursuing the Colombian guerilla. Only the Colombian Army has not crossed the border, yet. For these results, on which the Venezuelan government has kept a strange silence, he has received death threats and was attacked by some of Chavez supporters blaming him for the death of a suspected extortionist. That the death looks more like a mob like settling did not perturb these people preferring to blame Giusti and perhaps distract form his other findings.
