Speaking Arabic in public; or: don't say Yallah

You may have heard about the imams who got taken off a plane in the US (Minneapolis) because some passenger thought they were suspicious. Apparently:

Before passengers boarded, one became alarmed by an overheard discussion. "They seemed angry," he wrote in a police statement. "Mentioned 'U.S.' and 'killing Saddam.' Two men then swore slightly under their breath/mumbled. They spoke Arabic again. The gate called boarding for the flight. The men then chanted 'Allah, Allah, Allah.'"

It's bizarre the way that "They spoke Arabic again" seems to be characterised as somehow suspicious in itself - but the part that really makes me think "duhhhh!" is "The gate called boarding for the flight. The men then chanted 'Allah, Allah, Allah.'" It's obvious what they must really have been saying (although I haven't seen any paper point this out): Yallah, yallah, meaning "come on! let's go!". If even the use of the word "Allah" alarms some paranoid passengers, then Arabs will be hard-pressed to speak at all - between inshallah, hamdulillah, and bismillah alone (let alone yallah or wallah) you could easily reach at least one mention of "Allah" every couple of sentences in a completely mundane conversation! I hope this is an isolated instance rather than a trend.

In related news, speaking Yan-Nhangu is apparently suspicious as well...

In unrelated news, I thought Tulugaq's Google Map of Inupiaq was pretty cool, as is Sydney Place Names - I hope this is a trend.
