About

Prosecutors argued that bombs may have been built at least partly at the apartment. The defense challenged comparisons between household tapes and sealants and bombing debris; the government acknowledged that these established consistent class characteristics, not source-specific matches. Dzhokhar's residence there was also disputed in discovery and exhibit-label arguments.
