I’m sure it’s bad all around
Can you ask yourself why you assume this? Do you think you based your assumption on what you have previously been told about Iran by the same people who are making up numbers like 10,000 and 2,000?
Yes people have died and that is bad but many of them were probably killed by the rioters not police and the ones the police have killed were likely directly participating in violent acts. There are reports of police having beheaded by "protestors." "bad all round" would imply that none of the deaths were justified.
Iranian police in riot gear can kill as many people with small arms as isisrael does with jets bombs and tanks. This is why israel is so scared of Iran.
