According to the AP [...] a pregnant woman will be "brought before the committee and an ultrasound image of her uterus will be projected onto a screen" with the heartbeat shown in color. Faith2Action president Janet Folger Porter says the intent is to show legislators who will be affected by the bill. If that's the case, aren't there sentient beings, like, say, the people that will have to raise it for the next eighteen years that could use actual words to testify?
What's next? Sperm testifying about how sad they are never to have made it to an egg?
If The Fetus©™ fetishists and catholic zealots BBW and John 'Sperm Holocaust' Pacheco had their way, all menstruating females would be forced to collect every single drop of their monthly flow and bring it to a government inspection station. No woman would escape the ideologically-motivated scrutiny of her reproductive apparatus, also known as the ovaries + the uterus.
Update: my virtual roomie provided a link to pharyngula's post about those rightwingnutjobs and something jumped out at me.
Early ultrasound examinations will primarily detect the presence of the extraembryonic sac, not the embryo itself. It's too small. Around 5 weeks, you might be able to see a fuzzy small blob with a flutter that is the beating heart, but that's about it, and you do have to use transvaginal ultrasound to pick it up — that is, you have to insert the ultrasound probe deep into the vagina.
Got that? In order to get the maximum blobby F/X, the ultrasound probes would have to be inserted deep in the pregnant women's respective vaginas. No sacrifice too great for BABEEZ! it would seem. Betcha most of those male RepubliCon Ohio legislators will get their rocks off on that. In fact, that's probably why they've allowed this histrionic display.
