I was held for two hours. The first round of questions was about my views on Hamas. Then the agents wished to know whether I thought Israel’s actions in the Gaza Strip amount to genocide and what I think of the slogan “Palestine should be free from the river to the sea”. I said yes, I do think Israel is committing genocide. As to the slogan, I said that in my view people anywhere in the world should be free.
Then the agents interrogated me about who I know in the Arab American and Muslim American community. They asked me to provide them with telephone numbers, took my phone away for quite a long period and asked to wait until they made some phone calls before they let me go.
