There is a big difference between the '56 revolution and these days prtests.
In '56 the nation was united against the Sovjet-regime. 3 Years after
Stalin's death, the nation had a chance to go on its own way. The some of the occupation forces from WW2 were still in the country. Moskva had big influence on Hungary. It is said that Hungary was an "autonom" sovjet-region.
These days protesters are not united (not even on the Kossuth square). Here, now there is a democracy. There was no rifle to pushed to my head to put my vote to the good place. Meanwhile most of the country was mislead by the prevoius goverment about the state of the coutnry. And the political opposition side also misleaded the voters.
Lot of life, soul were ruined in '56. Those people who still alive, are angry. They encourage the younger protesters, but I think they forgot something these kids are not the same as the youngs were in '56.
In '56 there was no law about rights of assembly, every protests was illegal. That's what I think good to revolt against.
Now there are official rules, how to make demostration against anything. There are few things when you can't demonstrate, like protests against ethnical groups, sympatize with war-crime banned.
One can protest against the goverment, go to the police, make your arragement for the place and time, make your topics and possibly you get your permission to protest.
The Hungarian Helsinki Commite said the police intervention against the yesterday demostration/(riot) was legal. The protesters violated the right of assembly law, and I think they violated the right to a peaceful evening for the inhabitans of the city.
Were the police force was over-power? Well I don't think so.
Is it unique to use rubber bullets in Europe? I made a goggle search with "rubber bullets Paris" and "rubber bullets Berlin". There was matches.
The rioters complaining there were unarmed. Lucky for all of us. Why did the police use tear gas against unarmed protesters? Because this is a proper way to dissmiss an
illegal demonstration.
Unfortunately the police inpinged in several cases. 2 investigation already started against policemen and 36 more will probably start.
In other public forum I would probably get a 'kommunist-worshipper' or something worse attribute for my next sentence:
Thanks the police, that they did their job, and tried to make this city safer.
and for the last:
Every rioters should think about difference crushing a revolution and dismiss an illegal demonstration. And think again before going to sleep.
