Reading Visual Texts Critically

I thought this reading selection was pretty interesting. I never thought of the different opinions and views people get from looking at a picture, or other type of visual, as a form of argument. But now, the more I think about it, it is very likely that two people look at a picture, have different opinions, and then proceed to argue away.
I was also very interested in how you can interpret a picture one way, and then when you read the caption, it is something very different then what appears. Like the picture of the youth wading through the water with a trash bag. It looks as if he is helpless, or lost, in search of necessities. But later they mention that he was looting a grocery store. I could not believe this, thinking about what I had perceived beforehand.
I also would like to comment on the picture of the gun. The ad says "A gun in the home is much more likely to kill a family member than to kill an intruder" (69). This is a very controversial statement. I do not agree. Most sensible people are not going to just leave their gun out and about. It will be well concealed spot. It is our right to bear arms and protect ourselves. However, if you choose to own one, a huge responsibility comes with.
