If they do storm the parliament then the nation would expect the police and paramilitary forces to stop the protesters even if they have to use violent means. Other then getting their supporters killed I don’t think they would achieve anything. The army cannot takeover if the government wants to maintain the law and order. Protecting Parliament is something that most of us would expect from the government. Nobody can be allowed to take the law into their own hands. Army cannot side with the troublemakers without some negative impact on its reputation.
