Question: According to the provisions of the "Public Security Management Punishment Law", please answer what are the illegalities in this case? Please briefly explain why.

1. Dong paid a deposit of 2,500 yuan and used his wife as the guarantor. This is a double guarantee. The guarantor guarantee and the deposit guarantee should not be used at the same time.

2. The public security organs should send the person being punished to a detention center for custody and should not allow the person concerned to go there on his own.

3. After the person being punished does not violate the regulations and accepts the punishment on time, the deposit shall be returned in full. The absence of an error in the penalty cannot be a reason for refusing to refund the security deposit.
