A cartel using a SAM against a US civilian aircraft would massively solidify public opinion against them just like 9/11 or the Iran hostage crisis. The US has been trying to extent the "foreign terrorist" label and casus belli to drug activities forever to justify military operations (ex. the "arrest" of Maduro was for drugs, not oil/Cuba/political stuff). That would be a massive self-own on the cartels part. (And if it did happen, just like 9/11, it would be used as justification for anything even remotely immigration or drug related at every level.)
