I doubt a response team in Haiti speak English with that accent - let alone would use English over a megaphone.
Could the megaphone be a pre-recorded recording designed to delay identification of the perpetrators?

Could there be some kind of DEA SWAT team or something that was stationed there that may have been called?

Could be. One possibility is that is there were Americans involved, but they were private mercenaries (e.g. https://www.buzzfeednews.com/article/aramroston/mercenaries-...). It sounds like there are also similar private Latin American mercenaries (e.g. https://www.nytimes.com/2015/11/26/world/middleeast/emirates...). The Miami Herald article says the Haitian government is saying these were mercenaries, not DEA agents. It also sounds like this president was highly unpopular and arguably illegitimate, so he likely had a lot of enemies. It's not inconceivable that some those may have decided to hire a mercenary group for an assassination. Maybe they hired a mixed group, which would explain the use of Spanish and English.
Maybe this unlucky guy in the floor was one and just nobody care enough about them to mention them?.
