re: "For decades black males have been locked behind bars by the hundreds of thousands, arrested in disproportionate numbers."
While I do believe you're right, liberals (including you) do a lousy job of making that case. Perhaps that's because, as we've seen on this board, liberals don't seem to have a good grasp of either facts or logic.
Blacks are involved in a disproportionate number of CRIMES, clo. So of course they're arrested disproportionately (per 100,000) to members of other races.
Is racism the reason they commit so many crimes? Of course not. Black culture and widespread poverty among blacks fosters criminal behavior.
Racism plays a role in why black individuals are looked upon with greater suspicion and treated more harshly by the authorities than members of other races. This is wrong... and I wish I knew how to stop it.
When you post stats and articles like the one you just did, all you accomplish is to make rational people blow off your arguments (and the entire issue) as invalid. After all, if YOU don't take the problem and its cause seriously, why should anyone else?
There are several possible injustices you should investigate.
First, are the police being called in for incidents involving blacks more often than they are for incidents that do not? Remember - it is the PERCENTAGES that matter, not the numbers.
Second, are the police more likely to make an arrest when blacks are involved than when blacks aren't involved?
Third, are D.A.s more likely to press for trial when blacks are involved than when they aren't?
Fourth, are judges and juries more likely to convict when blacks are involved than when they aren't?
Fifth, are blacks receiving harsher sentences for comparable convictions than are members of other races?
Sixth, are black offenders more likely to get into trouble again than convicted offenders of other races?
You need to reasearch and answer these questions before racism should be considered. I think racism DOES play a role, but until the percentages I just described are determined, it's very difficult to say how much of one.
