Maximip:

Seeing injustice and letting it go is what's spoiling this country.

Maxim you sound like a Grammar Man who is not afraid to NAK BIG GRAMMAR , to weaken the resolve of any Nigerian policeman who fails to accord you recognition as an Authority Figure At Large.

May I take this opportunity to remind you that my company markets a wide variety of kevlar body armor, suitable for Threat Level-3 operations.  A man of swashbuckling braveness like yourself must leave nothing to chance during those all-important police confrontations in which you engage to prove your "patriotism".

Depends on how much more you and your sister are willing to sacrifice in terms of time, money, effort. The road could be tough and you must know who or what the adversity is. Fifty years of impunity. However things are changing and people have begun to get justice.

It's not advisable to confront them at the moment cos that could be dangerous. Let them win initially then fight smart. This "police brutality" happens a lot and believe me, there are some officials at the top that want to see it end too but they need the help of victims to bring up the case to them.

At least we should try to fight back (not physically) even if we fail. Poster's sister could have nightmares, depression, or low self esteem cos of this.

I remember a driver that was slapped like 2 times by one soldier probably half his son's age, The guy cried for like 2 hrs after that not because of the physical pain but emotional pain. They should learn to respect civilians and not abuse their power.

I know how you are feeling man,if you have any friend or relation in the army,this would have been a simply case. But it's like this whatever you do,in the end you may never win,it's like someone i know who shot and killed an armed robber,who was part an 8 man gang that were attempting to gain entrance into his compound.He had a most unforgettable ordeal not at the hands of the armed robber (the rest took to there heels) but at that of the police,let me not go into details,but at the end he had to abandone his lovely home and disappear with his family,and opted to sell the property. I know it's upsetting but just let it go,you may endanger your sisters life!

1) Sue him for assault and infliction of bodily harm
2) Report the Matter to his superiors
3) Demand for compulsory apology to be published in a national newspaper
4) Ask for compensation
5) Apply the Moses law (an eye for an eye).
