Take time to listen to this. The lecture deals with anyone in a position of authourity who is unjust and oppressive. The practise of corruption and power hungry. Imam Abu Usama put the issue in proper perspective. he differenciate between Islam and those who create disgruntle element in soceity and leads to terrorism and criminnality.
The lecture is based on a book by Adahabe, May his soul rest in peace. injustice is a grave crime in Islam as well in other faiths. God will not forgive oppressors and those who aid and abate them.
