black people who come to europe and attack people [ireland]

ok this is what i dont get at all why do some black people come to Europe and cause trouble and attack people ? can you please answer that i mean come on they ran from there country because from the war and violence right ? then why on earth are they attacking people in this country ? what in the fuk is this ? ok well today my older brother has been attacked by a gang of black men in there 20's and i wander why i mean they had a fight 5 months ago and it was all over but today when he was coming back from the store they attacked him from behind and his in hospital now his face is blue it was 15 men vs him :( i think you can imagine the damage by now .... anyway this country is Ireland and the so called police does not do shit :( i might as well take a gun and put a bullet in all there black hairless heads -_- i wont let this go i must seek revenge one way or another anyways...... so why if they are thugs and attacking humans why did they come to Ireland ? i think a new law must be brought to Europe ... if a black or someone from a developing country attacks a human more then 3 strikes they should be returned to there country because they are not here for peace anymore they are here to cause trouble ... i think that law should be approved :(

irish police must stand up to these thugs, they arrest them for only 5 days max and they release them no matter what they do even if they kill someone ..... and these Irish cops dont even Carrie guns 

Ireland needs to stand up and open there eyes before its to late
