David Davis, Chicago City v. Robbins — Opinion of the Court
“ Was the building of this area a necessary encroachment on the street; and if so, were the proper steps taken to secure it so as to protect the public from injury? The fact that an improvement may become dangerous, and involve great hazard, is no argument against the propriety of making it. If by great care, and more than ordinary diligence, it can be made, and the public saved from harm, and it is also necessary, then the right to make it is solved. ”
