The term bomb overall is wrong. A bomb is a military weapon with a number of specifications. A bottle filled with dry ice is a probably human-carried improvised explosive device. The complete explosive device might have shrapnels, it might not, it might be big, it might be small. That needs to be specified further, because explosive devices include a very large group of devices. After learning that distinction, I found it rather adaequate. If a proper bomb went off in LAX, we'd be looking at a lot of rubble. When WW2 bombs are disarmed over here in germany, square kilometers are evacuated due to the danger of bombs. This is not necessarily the case for most improvised explosive devices.
