The crowd did not exactly gave power to army, in short after the president resigned the crowd turned into a mob. There was nothing else to do, protest archived more than what anything even thought was possible and now you have large group of people and a lot of burning buildings and they continue to burn more.
So now turn from politicians homes to the national bank, supreme court, telecoms office, etc. the targetting of courts is really suspicion since it felt so random. Almost like a deliberate attempt to destroyed documents and evidence.
Also a lot of prisons were broken with most prisoners escaping and the police force were pretty much done. So the army had to come forward to restore order. At least no coup or any suspicious action by the army, they actually have been really helpful for now. But things might turn anywhere.
Also that twitter account is random as hell and something I discovered in hexbear. Don't think anyone got a clue on whats the deal with them.
I looked into the account you linked but it showed zero post for me and created few days ago so got really confused. Tried googling it and found no result.
SAFAL might be something that just exist on twitter perhaps. most people here don't use it at all and stuck to fb, and its same with me so had no idea about that group.
But its a whole Different world on FB and in ground so thought it was parody account. there is no 'revolution' here. Army has asked for a representative from 'Gen Z' group and former chief justice Sushila Karki was chosen. Won't describe how the decision was made since it really need leanthy explanation (involves a discord group with around 10k live chat members that went for 11 hours. Fucking wild but somehow a good thing in the end)
Also everything looks like a color revolution here, hell even CIA might be confused on when they planned the entire thing but all of this is somehow developing naturally
