1. Street demonstrations can bring down Governments. This we know from the Arab Spring. But we should also know that setting up a new Government to replace the old Government is not as easy.
2. There will always be people who will not agree with the new Government, no matter if the Government is democratically elected or not. The losers in the bid for power will always accuse the winners of cheating and frauds of all kinds. They will demand for new elections, or a re-count or whatever.
3. If their demand is not agreed to then they will take to the streets in continuous and even violent demonstrations, supplemented with strikes and sundry disorders. They know that if the demonstrations are big enough, the police cannot act against them. If the police try, they will resist and become violent. If the police react with violence than their foreign backers will accuse the police of brutality.
4. In many instances the police had to withdraw or they may be directed to withdraw. They become disinclined to carry out their duties. Some people would take advantage of this by committing minor crimes. The people would feel insecure.
5. If on the other hand new elections are held, and the former losers win, the new losers will accuse the winners of cheating, of fraud etc. They will hold street demonstrations and strikes and do everything possible to bring down the Government. And so it would go on.
6. The net result would be continuous turmoil in the country. There would be no growth. Poverty will spread. The country may have to beg for aid or borrow. In the end it loses its independence.
7. But of course this is a small price to pay for the right to bring down governments through democratic street demonstrations.
8. Perhaps it would be better if governments are chosen through street demonstrations. It would probably be less fraudulent.
