L, F, What's the Difference?

I'm reading a book about disaster management and there a couple of places where what should  be an l is actually an f. The first one isn't so bad. It says:

In a number of disasters, many fives have been saved, even in the face of tremendous property losses, because the affected population received advanced warning

But the second one is worse.

Pre-arranged agreements with the media provide the public with toll-free numbers to these regional information centers where they might learn if their relatives are fisted as known fatalities, or if relocated or injured, where they are now.
