This sentence overstates the death toll from the November 1992 Christine discotheque attack.

Contemporaneous coverage does not report eight Tijuana Cartel members killed. Instead:

• A 1992 UPI report on the Puerto Vallarta disco shooting says the attack "killing six people and injuring three others".
• A 1993 Los Angeles Times reconstruction of the same attack says the gunmen "shot up the restaurant with hundreds of rounds" and that "Six people died; Arellano escaped."

Those sources contradict the article's claim that eight Tijuana Cartel members were killed. The best-supported reported death toll is six total fatalities.

This sentence misstates the death toll and victim breakdown in the Guadalajara airport shooting.

Reliable contemporaneous reporting says:

• A Los Angeles Times report from May 25, 1993 states that "A Roman Catholic cardinal and six other people were killed" at the airport — i.e., seven total deaths, not six including the cardinal.
• A June 1993 UPI report likewise says the shootout killed "a Roman Catholic Cardinal and six others" and further describes the dead as "two gunmen and five bystanders, including Posadas Ocampo."

So the article's claim that six civilians were killed is inaccurate. Contemporary reporting supports seven total deaths, and at least one of the main early accounts says the dead were not all civilians.
