Being reasonable about it

These three white guys walked into this 7-11 in Oak Park and . . .

. . . approached the clerk. One of the men pointed a black handgun at the clerk, another said give him the money or he will shoot you, according to police reports. The clerk triggered the silent alarm and fled to the back of the store.

There’s more:

While leaving the store, the three men saw a man servicing an ATM and demanded that he open it and retrieve money. When the service man said he could not open the machine, one of the robbers hit him in the back of the head with an unknown object, causing a laceration. The man was transported to the hospital.

But the whole thing worked out badly for them:

The three men left empty-handed and were not found when police arrived.

So they had to go by the clerk’s and ATM service man’s description, which was not bad as those things go. The gun was black, as above, where what one of them said is also narrated, and were “in their late-teens” and “wearing hats, black jackets and blue jeans.” Hmm, black gun and jackets, blue jeans.

But neither witness noticed if they were black, white, or other! Or they noticed but preferred not to say. Or they told the reporter and swore him to secrecy.

Anyhow, I assume they were white, because there are more white people in Oak Park than any other. It stands to reason.
