1 Subjectively, it depends on you, and you have great initiative in this matter.
Personally, I think I can ask for it, or even more. Of course, you should know each other's family situation in advance, and you should decide according to your own situation. You can't let the other side talk. You still need 50 thousand, which is a bit unreasonable. After all, parents are innocent.
The other party has not committed intentional injury. This is a typical crime of provoking trouble, which is much more serious than the crime of intentional injury!
If you insist on investigating, it's a public prosecution case and a criminal offence. They may not be expelled from school, but what is certain is that they can't join the party and join the army for life, and their criminal records are also certain. In view of the fact that this incident is not intentional injury and the other party's attitude is bad, if no agreement can be reached, the possibility of probation is very small, and the possibility of imprisonment or criminal detention is very high. Once sentenced to actual punishment, most of them will be expelled from school.
To tell the truth, even if an agreement is reached, if you still want to hold them accountable, they will still be prosecuted, but they may be sentenced to probation.
You have handled a lot in this matter, that is to say, you have a lot of chips.
(1) You don't mediate and insist on accountability, so basically they are in jail, and they have to accompany you to get money when they are in jail;
(2) You mediate, but they don't give much money, so basically: the other party is still being investigated for responsibility, but it can be handled lightly, and it is more likely to be sentenced to probation.
(3) You mediate, they meet all your requirements, and you issue a written letter of understanding, so it is possible not to pursue criminal responsibility, which requires leniency from public security organs and procuratorial organs, because this is a crime of stirring up trouble, not a general crime of intentional injury.
You have the relationship with the procuratorate, and even the public security organs will give you three points. You can say that the initiative is all yours.
Even if the public security does not file a case for investigation, the procuratorate can ask the public security to file a case for investigation, and the public security must obey.
Personal suggestion: among the three college students, those with good mentality can earn more money, while those with relatively poor mentality can earn less money. After all, some families do have difficulties, but people really feel that they have to compensate you, so forget it. Some people have money at home, but they are just not active. This should be treated differently, and they can actively compensate. And if they have a good attitude, you will not hold them accountable and issue a written letter of understanding. Those who are not active will not be held accountable.
In addition, a written letter of understanding can be issued separately, and it is not necessary for three people to be tied together.
