This is the kind of indignation that Macri's voters typically won't feel for working class kids (the dark-skinned ones, anyway).
But there's more.
The are two public officials belonging to the PRO (Macri's party) with ties to the Time Warp rave in which the five youths died as a result of adulterated ecstasy - the event that triggered this ban.
The first official in question, Carmen Polledo, is head of the PRO (Macri's party) caucus in the Buenos Aires City Legislature. Her husband, Fernando, is co-owner of the firm that operates the Costa Salguero complex where the tradey took place. The Polledos also appeared as Mossack Fonseca offshore banking clients in the recent Panama Papers scandal.
The second official, Director of the Buenos Aires Province Cultural Institute Alejandro Gómez, had in fact already been indicted for the deaths in 1999 of two young people in a rock concert (he was later acquitted). Gómez - who has no experience in the arts at all - was appointed by Governor María Vidal, an overambitious Bible thumper in the vein of a Carly Fiorina; Vidal is being groomed by Macri to succeed him in 2023 (assuming he's reelected, which is unlikely).

Macri, as you can imagine, is under pressure to "do something" - especially since he himself called for the impeachment of the mayor during the horrific 2004 Cromañón disco fire in which 200 died (and that particular mayor had no ties to the event at all, unlike Macri).
I also should note that this ban - which went to the absurd lengths of banning all such events, be they raves or tango - was overturned on appeal this afternoon. Dance the night away, Buenos Aires!
