“Allah” means “god” in Arabic. Arab Christians use the word as well. We might not be happy about it because we know that muslims are thinking of a very different creator than we do, but that is the accepted translation.
Now, if they had left the Arabic text in place and inserted “God” where “Allah” is you’d have a point:
“Derka derke falllaha God derka hwachhh al derka.”
Yeah, that would look weird.
The Mohammedan perp was speaking English. He said “Allah” because that is what he meant.
How come when Muslims speak English they still use Allah?
That is their lie, they say we call our God “Allah” because Allah means God in Arabic. They will never call God “God” when speaking English, even if they do not know how to speak Arabic.
