The particular section cites: a) a Vancouver Sun article from 2008; b) a blog post from 2009; c) a Globe and Mail article from 2008; and d) a Washington Post article from 2008. All of these are somewhat speculative. It also cites a Customs and Border Patrol policy paper which affirms that customs has the right to search people as they enter the country.
Also part of the wikipedia entry is a quote from a European Commission fact sheet that directly counters the notion that ACTA will lead to the wide-spread searching of iPods of consumers.
If you want to argue that something is draconian and will force (not merely allow) searches, then at least come up with something more substantial than wikipedia.
